How Calico Cats Could Help Cure Obesity

Calico cats, with their funky mix of orange, black and white fur, could one day help humans to lose weight.

Couch potato kitties hardly seem suited to the task, but the connection comes from their unique chromosome structure, according to research presented today at the 58th Annual Biophysical Society Meeting in San Francisco.

Elizabeth Smith of the University of California San Francisco and her colleagues explain that calico cats have an orange fur color gene on one of their X chromosomes and a black fur color gene on the other, so that the random silencing of one of the X’s in each cell creates their distinctive patchwork coats.”
