Epigenetics and the Calico Cat

 
This is our friendly calico cat. She lives on the farm where we are staying. Almost all calico cats are female—do you know why? It has something to do with epigenetics.

See: Calico Cats—it's one of my most popular postings.

Can anyone explain how some very rare calico cats might be male?
