Can the color of cat’s eyes be inherited

       Because the pupil of cat’s eye changes in a day and night with the intensity of external light periodic changes. The details are as follows: at noon in the day, the light is strong, the pupil shrinks, showing a vertical line; at night, when the light is weak, the pupil is fully enlarged to be round, and other moments are oval in different degrees.

       Because the cat eye pupil is very big, is responsible for the pupil contraction muscle is very developed, the contraction is particularly strong. The cat’s function of changing three times a day is accomplished by the powerful dilation and contraction of the pupil.

       It can adjust the intensity of the light entering the eyes and keep it at a level sufficient to excite the nerves, so that the cat can clearly see all kinds of objects outside in the day and night. This is of great significance to the cat’s night activities and foraging, so sometimes there is a slight difference.

       First of all, not all Persian cats have Mandarin Duck eyes. Most of the Persian cats with mandarin duck eyes are white fur. What’s more, most of the cats with mandarin duck eyes are male! (because the probability of gene mutation is very small, it can also be said that they are all * and not only Persian cats have Mandarin Duck eyes, but also other cats. The color of two eyes of purebred cats is the same, and Mandarin Duck eyes are generally considered to be caused by. Most of these cats (Linqing, China or Ankara, Turkey) are genetically deficient, with beautiful blue eyes and deaf ears. So people crossbreed yellow eyed white cats with this kind of cat to breed mandarin duck eyes, a yellow and a blue eyed white long haired cat, there is no defect of deafness. The eye color of Persian cat depends on the color of its fur. It is generally believed that the eye color of Persian cat includes blue, green, copper, gold, amber, strange color, and two eyes have different colors (namely mandarin duck eyes). The coat color of mandarin duck eyed Persian cat is usually white. Cats with green, amber and golden eyes usually belong to the silver grey coat color system. The purer and darker the color of all kinds of eyes is better, and the color uniformity of two eyes is better.

       The question of what colors cats can see has always been puzzling. Today, it is not difficult to understand.

       The color that animals can see is determined by the wavelength of light that the retina can distinguish. Cat’s eyes can distinguish blue-green light, which is different from human eyes. Human eyes can distinguish three kinds of light (namely, three primary colors: green, orange and purple). The three primary colors in art can match any color. The three primary colors of light are the same, but the two kinds of trichromatic lights are not mixed Color, but the common color of the two kinds of light (blue and yellow reflect green light, red and yellow reflect orange light, so orange light and green light are mixed, resulting in yellow. This is why all three primary colors are mixed to produce white light £¼ the reason why sunlight is white is that it has all three kinds of primary colors £¾, no light is black, opposite to the three primary colors of Art). Having said so much, I just want to say that the color that seems most irrelevant to green may reflect green light, because if green light is combined with other color lights, yellow and blue may appear.

       The blue-green color light that cats can distinguish makes its world rich in green, blue and yellow, but it is also clear-cut. In fact, it is reasonable to say that the cat’s world is only green. However, it can’t regard the objects lacking of green elements as green (such as human faces). Human faces are similar to tan (yellow and blue, but yellow is more mixed) in the eyes of cats And maroon, like bright red apples that don’t reflect green light at all, can be black in a cat’s eye. In other words, the cat’s world lacks bright colors, but it does not mean that there is only pure green. In a completely warm environment (with more red and yellow), the cat’s eyes are relatively dim (because the cat can distinguish less blue and green light reflected).

       There are two kinds of stem cells in the retina of animals, which can sense the intensity of light and the vertebral body cells that can sense the color of light. There are more rod cells in cat’s eyes than in humans. Moreover, the cat’s retina is in front of the eyeball, and the light that enters the eye through the retina can be reflected to the retina again. Therefore, even if there is a little faint star light, the cat can see it. That’s why cats can see it It can see at night, because the lowest light intensity a cat can see is one sixth that of a human being. At night, however, cats can’t do anything about objects that don’t reflect any light (or blue-green light), such as brown mice with protective colors (Tan reflects red and blue, and yellow, but more red) and red mice (if any).

       By the way, dogs,

       For dogs, dogs are not really color blind. There are more rod cells in their eyes than vertebrae cells, so they pay more attention to distinguish light intensity. In other words, the so-called world of dogs is black and white. However, scientists have proved that dogs can also distinguish colors, but color has little significance for them. If bright objects really appear, what dogs can see is just pink.

       See some color lists about the colors of cats. But only solid color, can’t find all colors of the color list, consult many people said that did not see the full color. At that time, it was strange that the cats I saw had different colors and patterns, and they had everything. If it is not the match of solid color and solid color, what color will be produced, and for example, black and black will produce blue, then why? What’s the chance of blue.

       All of a sudden I wanted to know. Out of great curiosity, I’d like to make a watch of all kinds. Because I couldn’t find the ready-made information, I read about genetics, searched for the color genes of cats, and calculated them according to the genetic formula. Then suddenly understand that the original solid color meter is the universal meter. All the colorful cats we see in our eyes follow the rules of the solid color chart. Knowing the cat’s coat color control genes, the color of offspring can be calculated by matching all colors. And it’s not very profound knowledge. Anyone can calculate it by himself. … I used to think that the color of a cat is not necessarily inherited from its parents, but can be passed on to grandparents or even further away. I thought that there are countless kinds of colors in cats. Only after understanding, did we understand that the color of cats must be inherited from their parents, and that only the recessive genes that control the color depth and change can be passed on to the previous generations. That is to say, yellow cats and yellow cats can not produce black cats, only yellow cats, but not red cats. Red cats and red cats can produce yellow cats, but they can’t produce black cats of different colors. Because I’m not a cat genetics expert. The genetic data about the color matching of cats are compiled and calculated by myself, so the error is inevitable. All information here is not posted. All of them are purely personal views, which can not be said to be right, let alone authoritative. There are only two colors for cats, red and black. There is no other color. The faded color of red is milky. The fade color of black is blue. Color in cats is inherited on the sex chromosome. High school biology teacher taught a pair of chromosomes to control the sex of a person. The same is true for cats. The common XY is represented, and the female is represented by XX. Offspring take a letter from their parents. If you take y from your father and X from your mother (you can only take x from your mother), you will get XY, and the offspring will be male. If you get x from dad, the offspring is XX, that is female. Because the cat’s color is on the sex chromosome, the cat’s sex chromosome has no color. That is to say, X can be colored. It can be red or black. Let’s take an example: a pure red male cat matches a pure black female cat. The red male cat’s chromosome color is x (red) y (colorless) and the black female cat is x (black) x (black)… Then if their kittens are male (male is XY): it means that the kitten must take a Y from his father, and Y is colorless. So kittens can’t inherit any of the colors of male cats. Because mom is black. So any x the kitten takes on her mother is black. In other words, it must be black. (there may be blue, brown, light, key colors, and we’ll discuss these later)… If they’re kittens, they’re female (XX): you should know. I will take an X on my father, that is, I will take my father’s red color, my mother will also take an X, and my mother’s black color will also be taken. So the kitten must be two-color. For example, if a red male cat x (red) y (none) and a red black female cat match x (red) x (black), then the same calculation, the little male cat can take a color on his mother, can take x (red) or X (black), that is to say, the little male cat is pure black or pure red. The kitten must have a red on her father’s body and any color on her mother’s body. In other words, the kitten can be red black or pure red. Take the red male cat and the red black female cat for example, and make a chart, which should be better understood… Therefore, it is impossible for the little male cat to get any color from his father, that is to say, the little male cat can only inherit the color of the female cat. Because the little male cat can only get one color from his mother, the male cat must be monochromatic (explained below for the two-color male cat). Kittens can get at most two colors, red and black, because they inherit one color from their parents. So the two-color cat must be a female cat. According to the above rules, you can easily calculate any pure color. … but blue and cream are on the solid color list. I personally think that blue and milk color are the result of the desalination gene on the autosomal, and have nothing to do with the color on the cat’s original sex chromosome. The CFA results are more easily understood if the two basic colors match black. Other colors only weaken the effect of gene and make black and red appear different degrees of desalination. For example, black cats will produce black, dark blue, light blue and so on. In fact, they are all black, and the distribution of pigment is different, thus producing different visual colors. CFA’s pure color table actually takes the color genes on the cat’s sex chromosomes and the desalination genes on the autosomal into account. However, there are not only desalination genes on autosomal chromosomes, but also other genes such as whole white, tiger spot, white spot, terminal color, gradients and so on. The function of desalination gene is the same as that of desalination gene, which adds different characteristics to the color inherited by cats. For example, the color list says that black male and red male can produce black male and blue male. If blue is one of the possible types, there are also chances to produce chocolate focused kittens and brown male cats. Although such opportunities are rare, there are also fewer opportunities for blue male cats. Only if the black female cat is matched with a milky male cat, it will have a little more chance. So I think the results of the color list are not comprehensive. Other colors: all white: all white used to be a cat’s color. It’s not. The pure white cat turned out to be colored. It’s just that another gene makes the cat’s original color invisible, so it looks like it’s all white. If the all white gene doesn’t work, the kitten will inherit it according to the original color of the big cat. White spot: in our eyes, black and white, red and white, three flowers, all have a piece of white. In fact, it’s the same as all white. In my opinion, white is not the color of a cat. If you don’t count color, you can only have two colors. So it’s right to say that there are no male cats for Maomao, blue milk and Sanhua. Because these colors have two different colors except white. Male cats can only have one color except white. So a two-color male cat must have a white color. The gene is not on the sex chromosome and has nothing to do with the cat’s original color and gender. Blue, cream: blue is a faded color of black. Milk color is the fade color of red. In fact, it is also another gene effect, so that the color of the cat where the pigment density is reduced, there is a fade color. The gene is not on the sex chromosome and has nothing to do with the cat’s original color and gender. Tiger spot: the same as above, a kind of tiger spot gene function, in the cat’s original color function, the appearance of tiger stripes. For example, the cat with brown tiger spots was originally black. Because of the action of tiger spot gene, it became brown tiger spot. The brown tiger spot looks yellow and black. In fact, the cat’s original color is only black due to the action of tiger spot gene (any tiger spot can only be counted as one color). If this brown tabby cat matches a pure black one. If there is no tiger spot gene in the kitten. Both male and female must be pure black cats. The gene is not on the sex chromosome and has nothing to do with the cat’s original color and gender.

       Key color: same as above. A gene effect of albinism. But the most special thing about this gene is the way it whitens. It starts to work in the kitten’s belly and is affected by the temperature of the mother. The lower temperature parts of the kitten’s body show deep coloring, while the parts with higher body temperature show relatively shallow coloring. Because of the high temperature in the mother’s environment, the kittens are very light at birth. The color of the eye is also affected by this gene and is always blue. Therefore, some Hippo horses are almost completely white, and some can vaguely see that the original color and pattern are determined by the temperature of the mother. Key colors look very special. But if it’s not with a cat in a key color. The kittens born will be inherited according to the original color of the key color. The gene is not on the sex chromosome and has nothing to do with the cat’s original color and gender. Gradient: no more explanation, same as tiger spot gene. The gene is not on the sex chromosome and has nothing to do with the cat’s original color and gender. To sum up. There are only two colors of red and black. All the original colors of cats are red, black or red black. The reason why we see cats that are so diverse is because other genes that control color work together. But none of these genes are on the sex chromosome and cannot change any of the original colors of cats.

       The color of kittens can only be inherited from their parents. It is impossible to skip the color of their parents for the next generation. Male cats cannot inherit the color of their father. A female cat must inherit a color from her parents. Ignore white. The male must be monochromatic. The female must be monochrome or bicolor. /P>

       Two different colors of eyes are typical of purebred Persian cats, and those with the same color of eyes, no matter how similar their appearance is to Persian cats, are bound to be mixed with other breeds of blood. The color of cat’s eyes is not much, generally green, light brown, blue, yellow, amber and so on.

       The color of Persian cat eyes is mainly affected by genetic factors. Many people believe that the color of the eyes of purebred Persian cats will be the same, while the Persian cats with mandarin duck eyes are generally considered to be £¢ male £¢. Therefore, the Yellow eyed white cat was used to cross with this kind of cat to breed mandarin duck eyes, a yellow and a blue eye white long haired cat.

       According to the study, Persian cats with mandarin duck eyes have white hair, while cats with green, amber and golden eyes generally belong to the silver gray color system. Moreover, the purer the color of each eye, the darker the color, the better the variety.

       This ~ normal, not too normal~

       Does your cat have a blue eye?

       A lot of blue eyed cats are deaf. Like you, two eyes are different colors. If one eye is blue, the corresponding ear may not be able to hear.

       You can try it, I hope it is not deaf, if unfortunately, I predict

       Then you should be glad that his other ear is intact.

       I don’t know if the cat’s deafness can be cured. You can consult a doctor. C
