Calico Kalinda!

by Kathryne on August 16, 2016

Kalinda is a beautiful long-haired Calico princess, and she knows it! This pretty kitty is 6 years old and Kalindadefinitely appreciates some royal-style pampering. She is affectionate, tolerates other cats, but definitely will be the alpha. She has a colorful personality that will warm your heart and keep you guessing.

Calico cats come in many shapes, patterns and sizes, but did you know that in order for a cat to be a calico, it has to be female?

There is DNA carried only on the X chromosome called the Orange Mutant Gene.  As with humans, female cats have paired sex chromosomes, XX, and male cats have XY sex chromosomes. Because female cats have XX chromosomes, sometimes the chromosomes will take turns being dominant in different areas of the body. The biology of it may be a little confusing, but basically what happens is when a cat is developing, one set of cells where an orange coat is dominant will divide and create a patch of orange, while right next to it a patch of cells where the tortoise-shell gene has been activated will create a patch of tortoise-shell coloring.

Think about it, have you ever met a male calico? (It is possible with another mutation, but is extremely uncommon)

Here’s an article that explains the occurrence of a calico pattern in greater detail, for those of you who are interested.

Another unique thing about calico cats is that no two are alike! Seriously, when calico cats have been cloned, they still appear with different coat patterns. That’s because there is no way to control which and where an X chromosome will become activated.

Rainbow, a female calico, was cloned. Her clone, CC, developed with a significantly different coat pattern than Rainbow. The picture below is a picture of Rainbow with a young CC. And yes, they are really genetically identical! Their twin genotypes were even confirmed by a University of California, Davis geneticist.rainbow__cc__allie21

So if you are considering adopting Kalinda or any other calico for that matter, she (or that very rare he) will be unique to you in all the world.
