Question for the Color Genetic Mavens here

Postby madelyn » Wed Oct 15, 2008 12:32 pm

The horse is not a TB - but it is an interesting color puzzle.

My friend has a Quarter horse mare who is very nearly black but is registered as a chestnut. She has a bit of lightness around the edges - a hint of chestnut and/or gold - and the QH folks call that a "black chestnut." Last year she bred the mare to a buckskin stallion and this year she got a PERLINO filly.

Naturally the QH Association got all up in arms and started demanding DNA parentage verification (which was already done on the mare originally - ???) and are refusing to register the filly, etc. etc. etc. ad nauseum. My friend called me ALL UPSET and the only thing I could fathom was.... Well is it possible her nearly black mare is actually a smoky black? Genetically? Her sire is a palomino and her dam is a bay, I believe. Anyhow, in my dim understanding of color genetics, I believe it WOULD be possible to end up with a double dilute foal from a buckskin and a smoky black - n'est ce pas? Wouldn't the shortest distance between two points be to genetically test the mare for color and if she IS a smoky black (genetically) to have her registration corrected from chestnut to smoky black?

Any and all help with this puzzle is deeply appreciated.

Hope this may serve as a clarifying headstart. :D

To get a perlino, both parents have to contribute a cream dilute gene.

So if Daddy is a buckskin--Bay plus cream

Momma has to be --Something plus cream. She might be a very dark Chestnut Palomino. Or more likely a Smoky Black. Take a look at Donna's smokey black filly. From some of the photos I'd swear she's a bay.


Test the mare, send the reg papers + color test results + DNA results for the foal. If the mare doesn't come back with Cream, try testing for Champaign, or Pearl. She may have one of the odder dilutes.

Good luck

Sounds like mother is smoky Black, that would fit. Since all is testable now I would have the mother test.

Has the filly been color tested and proven to be a perlino?


And yes a Buckskin and a Smokey black could produce a perlino.

If you remove cream from the equation, the question would be could a bay and a black produce a bay? And the answer is yes of course, happens all the time.

Now if both parents contribute a cream gene, you have a perlino. If only one cream gene was donated, the filly would be another buckskin.

Good luck to your friend getting this sorted out.

sounds like a smoky black to me. My friend has a smoky black QH gelding, and he has orange tints to his ears and some other places.

Okay - where does one have a Color DNA test run and what is the cost?

This is a photo album for a palomino morgan mare and as you can see she looks nothing like a regular palomino. Her sire is a cremello and her dam is a liver chestnut.

this is her dam.

So the mare in question could still be a palomino, but like it's been said color testing is the only way to be sure of her true color.
