Dun factor and double creams
 
I was just wondering... I'm looking at a perlino filly. She is out of a smokey black mare (no idea of her dun factor) from a dunskin stallion. My question is how does the double dilute affect the dun factor? Would you still expect to see the typical dun markers?

They are on the coat but since the coat is so light, they are difficult to see. I saw a perlino dun on a website once. His leg barring was so faint it was barely visible and you could vaguely tell he had a dorsal stripe. Can't remember his name though, but they had him tested and he came up D/d.

Also, you would know if the mare carried dun because smoky grulla looks like regular grulla. She would be obvious.

There are some pictures of this double dilute stallion.

I don't know anything about dun factors, but that stallion is breathtaking!!!

Monty: Dun is a gene that dilute color similarly to cream. It also puts "primitive markings" on the horse such as shoulder barring, leg barring, cobwebbing on the face, and a dorsal stripe.

Well then I know the mare doesn't have dun factor. The filly has such a wooly coat right now I can't tell. I'll have to wait till she sheds out... if I get her, waiting on HERDA tests.

What's a "HERDA" test?

HERDA is a genetic disease in Quarter Horses that is associated with the Poco Bueno line. It stands for hereditary equine regional dermal asthenia. More information: Horse HERDA
