tricolor cats, “Calico” Also known as.

So why do these cute friends, who attract attention with their orange, white and black feathers, almost all female? Let’s explain the scientific reason.

The reason why tricolor cats are almost all female lies hidden in their genetic structure.

Let’s explain it in the simplest way. Genes that determine the color of a cat on the X chromosome is available.

Females have two X chromosomes (XX), while males also have one X and one Y chromosome (XY).

So if a woman has two different X chromosomes, she is carry both black and orange color genes makes it possible. The white color gene is determined by another gene.

Because females have two X chromosomes, this color combination is both black and orange It becomes possible.

Male cats have only one X chromosome black or orange They can have feathers.

It is also possible to see a tricolor tomcat, but this is quite rare as it is caused by a genetic mutation!

Studies Only one in 3,000 tricolor cats He claims to be a man.

The reason for this is that a very rare genetic mutation is required to make male cats tricolor. (Klinefelter syndrome) needs to happen.

A tomcat with Klinefelter syndrome, unlike others, have two X and one Y chromosome (XXY) If you have this, you can have all three colors.

Tomcats with the genetic mutation in question usually infertile It is stated that.
