Chimeras

The Chimera according to Greek mythology, was a monstrous fire-breathing hybrid creature of Lycia in Asia Minor, composed of the parts of more than one animal. It is usually depicted as a lion, with the head of a goat protruding from its back, and a tail that might end with a snake's head.

With animals, chimeras are the result of a genetic anomaly with one animal  having cells derived from two different cell lines. Brindle coloring in horses is extremely rare and in many cases is linked to spontaneous chimerism,  resulting in an animal with two sets of DNA, , with the brindle pattern being an expression of two different sets of equine coat color genes in one horse.

In 2011, Amaretto brought us their own version of the Chimera Brindle horse. The Black/Platinum Chimera Brindle, Brown/Red Chimera Brindle, Brown/Tan Chimera Brindle, Platinum/Black Chimera Brindle, Red/Brown Chimera Brindle and Tan/Brown Chimera Brindle are one set of many exciting possible Non-Starter coats that can come from breeding starter horses. You can have a chance at one of these exciting Non-Starter coated Chimera Brindles by breeding any horse with a starter horse or by breeding together two starter horses. 
Even though these coats have been put out to pasture, these coats CAN be passed on from existing lines.
