Calico Cat Fact

By xerocube | October 24, 2006

I heard an interesting tidbit of information yesterday… did you know that virtually all calico cats are female? I was not aware of that, so I used the intarweb to research this. Of course, we all know that the internet is full of facts, it’s just a matter of finding them. My intense 30 second search unearthed the following site:

The site briefly discusses the genetic makeup of calicos. From the site:

For the sex chromosomes, there is a battle for power. This is especially true for the X chromosome. If two X chromosomes are present, which determines female sex, one X chromosome will become inactivated at some point in fetal development. When this happens, all the cells descended from the activated X chromosome will have the same characteristics, including coat color.

So, there you have it – a drop of knowledge to broaden your horizon.
