Under normal circumstances, a cat needs equal parts of chromosomes from her parents. This is why we have tortoiseshell cats, calicos, torties bi-color, or tri-color varieties of cats. Females, on the other hand, have two X chromosomes and can have both red and black pigments. Male cats have only one X chromosome and can be either red or black depending on certain modifying factors. The red pigment (what we call orange) replaces the black or brown pigment. The X-chromosome often carries the orange gene. This is put in place by Mother Nature to balance things out.Īpart from gender, feline sex genes determine the color and pattern of the cat. Because females have two X chromosomes, one is often inactive. The Y-chromosome contains a special gene called SRY (sex-determining region Y) which leads to male development. ![]() The gender of your kitty is based on which chromosome they inherit from the father. This is the situation for all mammals, including cats. If you can recall your Biology 101 class, you probably remember that females have two X chromosomes and males have both X and Y chromosomes. To properly explain the phenomenon of mosaicism, a good understanding of feline sex chromosomes is necessary. In this guide, we will give you the ins and outs of mosaicism in cats. What causes this special coloring to come about in kitties? There are many situations with one of them being mosaicism. Imagine owning a calico or tabby cat with orange, black, and white on her body? She would turn heads everywhere she goes.
