Saw an ad about guaranteed colors from a stud?

Here's the ad. I took out some of the identifying info.
This is NOT my horse. I don't even know the people who have him.

Can they really DNA test a horse to guarantee certain colors?

Standing at stud: (age) Perlino walking horse colt grandson of (horse) this colt is out of registered TWH but I don't have papers on him. Has been DNA"d and guaranteed only buckskins and palomino's foals except when bred to a grey. (location) (stud fee)

Yes , being a perlino he is homozygous for the cream gene. He will throw the cream gene to his foals garanteed, no matter what color the mare.
Check out equine color genetics for more info on DNA, Color. There is also a color calcular to help predict foal colors.

If a horse is homozygous for certain genes you can increase the odds, but no, you can't guarantee like that. The stud being advertised is likely heterozygous for black and homozygous agouti- so he will never be able to produce a black foal (agouti will always turn it to a bay) but could produce a chestnut foal (on which agouti has no effect).

Since he's perlino, he's definitely going to pass along a cream gene, so the bay becomes a buckskin and the chestnut becomes a palomino.

What they're not taking to account is that the mare could also contribute a cream gene, which would produce a perlino or cremello. There are a number of other genes that could come from the mare that would affect the color- champagne, dun, pearl, silver, etc.

So for your average bay, black, or chestnut mare who's not hiding any other genes, you would be guaranteed a buckskin or palomino. But, breed any other color mare and the guarantee is out the window

Ugh.

Sorry, all I got was "I'm standing a grade, coloured, unproven stud horse cause he's COLOURED!!"

Ok. I was just wondering. I don't have any involvement in breeding and I don't really know anything about color/genetics in horses, just what I've retained from Biology 101. It was just a really strange ad so I thought I'd ask.
Thanks for the info.

My guy can can only throw bays, buckskin and perlino. I know because I had him color tested. I didn't care anyways, I didn't buy him for his color, I don't like buckskins all that much, but one of my mare owners wanted to know.

If you do enough testing, then yes, you can have horses that you can "guarantee" certain colours in the produce. This guy is obviously Ee AA CrCr, so he can sire red or black based, but his black based foals will then be affected by the agouti part, and always be bay or brown from there. Since he is CrCr, he can only pass cream to his foals, so they will always be at least single dilute. The thing missing from the ad is to narrow it down - he can only sire buckskin and palomino foals from non-cream mares, and then can sire palomino, buckskin, cremello and perlino foals from single cream mares.

I know :)
It's ok.
I hate stupid breeding too.

This color genetics stuff is fascinating. I'm going to have to spend some time reading about it. I never knew there were so many factors that influenced color.
