Cats colors and genetics

Cats colorsWhether postcard or not, it is not an artistic question but a genetic one. Without detracting from the beauty of these animals and not even wanting to reduce the magic of the legends that have been built around history in history Cats colors, it is interesting to know how they are formed. Who decides them and if they affect the nature of the animal itself.

Cats color and character

As anticipated, the Cats colors it has nothing to do with character, it is purely a genetic matter. The behavior of a cat, let's look into each other's eyes, is obvious that it is the result of very complex mind-body-environment interactions and which can also gradually lead to changes.

IS' poetic but not realistic to think that a feline, if you see black or brindle fur, develops psychological characteristics in one way or another.

It is proven that it is not possible to attribute specific behaviors to a color or design. Yet rumors are still often repeated as reliable: for example, it is said that black cats with red stripes have a temper, that red cats are particularly territorial and beige ones with colored appendages give a little snobbishness. They are all beliefs without scientific basis.

THE Cat colors and patterns depend on its genetic makeup: there is a set of genes that in the growth phase of the fetus begins to activate to "color" the cat that will be born. If it's not a question of character, it's not a question of race either: with some exceptions, color does not identify a breed and most breeds cover a wide range of possible colors.

There are several mating tables around, but this one is special and surpasses any imaginative legend.

Color change cats hair

That a cat changes color, it is strange, if not during the first phase of growth, when the extremities can start to color. European cats usually have a "base" coat, wild type, brown, which it is called brown or black tabby if it has black fishbone streaks. They are very popular cat colors even if common, but the reason for their preponderance lies in the fact that they are perfect for camouflaging in the grass, in the bushes or on the branch of a tree. Then, they are the genes to decide.

There is what makes the gray brindle cloaks (blue tabby) or completely gray (solid blue) and plays a big role in the case of Carthusian cat interacting with the dilution gene, capable of converting black into a greyish hue. Or, in other breeds, red in a cream / pink shade. There is the gene that replaces the brown / black bands with cream / red bands giving us the spectacle of red cats, much sought after these days.

Color cats and eyes

So large compared to the size of the head, the cat's eyes affect the overall appearance of the cat more than in other animals, both aesthetically and otherwise. There are felines with eyes of hazel or copper, even tending to yellow, with the years and the bad habit of wanting to create animals with the appearance that follow our desires, playing with genetics we have made sure that today there are colors of eyes that range from blue, to green, to orange.

In most cases the color of the eyes is not related to that of the coat although in some breeds there are standards that want to make simplistic associations that turn out to be true only in a few cases.

There is a case, one of the few, in which the blue color is almost mandatory, and I am referring to cats with mostly white fur. It is not a rule but the probability is high, this is explained by the presence of one form of albinism that generates a lack of pigmentation both in the hair and in the iris. It also causes dryness of the fluid present in the hearing receptors, so much so that white cats with blue eyes are often deaf.

White cats and black cats

Black cats if in Italy bring bad luck, if they cross the road, in UK they have the opposite effect, but only if they stand still at the door. It is not a different matter color perception: almost every country has its own truth about the color of cats, especially if it is black, also called solid black, the result of one genetic mutation that has transformed what appears as a brown "background" into black. The black cat is not black, if you look at it against the light, it is dark brown with "ghost" streaks that carry secret genetic information to those who can notice them.

Even the White cat, as mentioned, often hearing impaired, he is understood and described as a special animal. There is a gene that is believed to be the responsible for the production of white pieces and it is quite unpredictable.

When he wants, he does snow-colored patches appear By inhibiting the effect of any other antagonist gene, this moody character of the gene explains why in the universe of cats it is difficult to detect a certain regularity in white spots, even if consanguineous specimens are observed.
