This unique kitty boasts two different eye colors and a coat that is divided perfectly in half with two distinctive hues. It’s safe to say that this exceptional feline is likely to catch your attention and leave a lasting impression.
The Quimera cat is a truly unique and spectacular feline that seems to have been created by the cat gods themselves. It’s as if they thought, “Why settle for one cat when we can mix two?” Although we don’t know for sure what their exact thought process was, the end result is truly breathtaking. The cat has two different colored eyes and a furry face split down the middle with two different colors. It’s no wonder that it’s considered one of the most stunning cats out there.
According to PEOPLE, Quimera belongs to a rare group of cats that may or may not be chimeras. But what exactly is a chimera? According to Columbia University Professor of Genetics and Development, Virginia Papaioannou, a chimera is an individual made up of cells from at least two different original embryos. If these cells fuse together early enough, they will become a single organism with genetic input from two completely different individuals.
According to Papaioannou, Quimera and Venus, two viral cats known for their unique appearance, may belong to the calico cat family. The reason behind their striking appearance is a simple example of X-inactivation mosaicism coupled with a white spotting gene. All female mammals, unlike males who have an X and a Y chromosome, have two X chromosomes, but only one is active in each cell of the body. This balances out the effect of X chromosomes in males and females since females have twice as many, making it logical that half of theirs would be inactive.
The X chromosome in a cat contains a gene that determines fur color. For female cats, there is a mosaic expression of all the genes on the X chromosome, meaning half of them will express one version of the gene while the other half will express the other version. The inactivation process is random, resulting in orange and black mosaicism being highly visible. This pattern applies to other genes on the X chromosome with two different versions or alleles. According to Papaioannou, this does not make a cat a chimera, as it only has different active genetic components in its cells, making it a single individual. A chimera event would be much less likely and unusual.
According to Papaioannou, the reason behind their distinct eye colors may be attributed to the white spotting gene. He thinks that it’s affecting the eyes differently, with one having a normal color and the other appearing blue due to a lack of pigment. This piebald gene could be responsible for altering the eyes’ appearance in this unique way.
Quimera is undeniably one beautiful feline, whatever secrets may lie behind her captivating appearance. Take a gander at some of her resplendent photos below:
