Calico cats are actually super interesting from a genetic point of view.


Calico cats are actually super interesting from a genetic point of view. Girl cats have two X chromosomes, and one will inactivate a few days after conception. It inactivates randomly, leaving blotches of fur coded with one X chromosome, and the remaining fur coded with the other!

    In humans, activation of the X chromosomes is also random. If he gave color effects on skin, women would be even more mosaic than cats… :-)
