However, the fact is that the gene for Calico and Tortoiseshell is carried on the X chromosome only. The mother and father each pass one chromosome to the offspring during the reproduction process. The mother bears XX chromosomes and the father carries XY chromosomes. Like humans, the mother and father pass each to the offspring. This happens because of the XX sex chromosomes that the females carry and the XY of the males. Why are all Calicos/Tortoiseshells with these patterns female? On the other hand, chimera cats have two sets of DNA which make them Chimera. Therefore, tortoiseshell cats are not Chimera cats as they have their individual DNA. However, tortoiseshell cats naturally have a mosaic pattern in their coat which causes different colors. Though the coat pattern of Mosaic or Tortie cats might look like Chimera, they are not Chimera cats.Ĭhimera cats have two sets of DNA which makes the variation in the coat or eyes.

The condition of having different colored eyes for cats is called heterochromia. Why Are Some Chimera Cats Born With Distinct Eye Colors? Chimera cats have two unique DNA sets, which are also clearly visible on their face and body structure. It’s more like nature’s play combining two fraternal twins in one. Unlike this condition, Chimera cats are formed from two different fertilized embryos that combine and act as one. To be more specific, when a normal kitten forms in the womb, it comes from one fertilized egg.

Therefore, Chimera kittens take birth combining their DNA plus DNA from the second embryo. These cats have two sets of DNA because a couple of embryos fused early in the mother’s womb. What Causes the Chimera Phenomenon in Cats?Ĭhimera cat is two cats in one.

According to another definition: Chimera is any organism that has cells that are genetically different. The cells of a Chimera cat are genetically different from other organisms. The separation line between the two colors is sometimes amazingly straight.Įssentially, the Chimera is nature’s play by combining two cats in one. Have you ever wondered what makes one half of their face different from the other? And their eyes?!
