By decoding the genetics, any coat colour can be traced back to one of these two colours. You see, almost all calico cats are female which means that they have two X chromosomes in every cell. This can be partly due to feline genes. When the silver gene is present, the light bands are pale grey or nearly white. Not only are there many interacting genes, but genes sometimes do not express themselves fully, or conflict with one another. This is controlled by a different locus (S) than the black/orange fur colors. Two copies of every chromosome. Try. Furthermore, the mutations leading to a black coat are in the same gene family as those involved in human diseases like AIDS, so it may be that black cats … The black and orange patches that define the coloring of a calico cat beautifully illustrate the genetic mechanism known as "dosage compensation."
