Horse of a Different Color

[Joanne]

<BR>I had two unusual color combinations in my foals this year which I am still trying to understand. The first is a colt that was coffee colored at birth with High white stockings, bald face, and belly white that is apparently a splashed white overo pinto (all other pattern testing was negative i.e. LWO and sabino). Coloring wise he was tested as Homozygous for Cream AND Black!!!!! Making him what they call a smoky cream. So based on this when bred to a palomino the foal would be one of the following colors; buckskin, smoky black, smoky cream, or perlino; with or without splash white. When bred to a buckskin the foal would be one of the following colors; buckskin, perlino, smoky cream, smoky black. When bred to a bay you get either a smoky black or a buckskin.

The second is a colt that was tested and just came back as Homozygous for Bay AND Black. Bred to a palomino or a buckskin you are virtually assured of a buckskin or a bay. Bred to a cremello, a 100% buckskin.

These genetic tests are sure interesting. And the value of the knowledge for future breeding is amazing!

I think, correct me if I'm wrong,that a colt that is homozygous for agouti must pass that to his foals so he could not sire a smoky black regardless of what he is bred to. He will only have foals that carry the agouti gene so, buckskin or bay (since he is also homozygous for black he can't produce red based foals either)

He sure is a pretty little guy.

I stand corrected. Thank you for catching that. i redid his coat color calculation at Animal Genetics and edited the original post.

Thanks again!

This way it is even more impressive if you have a buckskin breeding program!!!

either way he looks like he is a boy to be proud of. Of course he could be bay with no homozygosity (is that a word?lol) and I'd still like him. I like bays and I really like that head of his.

This colt could still be carrying Sabino even tho he tested negative. The Sabino test available now, will only test for one of the Sabino genes, and there are others that there are no tests for yet. ;-)

they sure are beautiful!! I love trying to learn more about color patterns and color genes! Where do most of you get your color testing done and how expensive is it? Although, where I'm in Canada, maybe it would be more?

thanks for any info

Just because the first colt came back negative for LWO, couldn't he still be a frame?

In a word...No. He must carry LWO in order to be a frame.

Dona you are absolutely right that Bailey could carry a sabino gene we can not test for at this time. He has the high white stockings and bald face and belly white more consistent with the splashed white gene, though as he darkens we may see sabino type markings as well.

This is Bailey's sire, Pacific Celebrity. We did not learn he carried the cream gene until he had this foal.

He is LWO and sabino 1 positive, and carries one cream gene. We suspect he carries splashed white, but we are unable to test for it at this time.

His dam, China, is a smoky black with amber eyes.

We do our genetic testing at Animal Genetics.
