Coat Color Testing - what do I test for??

Hello everyone! I have a coat color question :)

I have a dunalino colt. His dam was a red dun and sire was a grullo. I recently had him tested through UC Davis for the Dun Zygosity Test. He came back D/N. There are some pictures of him here: Our Stallion - if that helps. Just a little history for you :)

My question is: There are so many different coat color tests I could have done through UC Davis. I'm just not sure which I should have this colt tested for. Any suggestions?

Thank you,

I would test him for Frame (LWO) first of all. Given that he is a QH, I would not breed a mare to him without knowing his frame status. You could also test him for splashed white, the test is new, and he probably has it. You could also test his agouti status, which is handy for mare owners who are looking for certain colours in a cross.

Don't bother testing for cream - you know he is Cr/cr, or for tobiano, since QHs don't have it, or for black - because he is red based, we know that he is e/e.

We all start somewhere Any time you have a question, just pop it up here somewhere. There are several members on here with very good knowledge of genetics, both of colour and of health.

On that note, you could also test for HYPP and HERDA. They are only in particular strains of QHs, and I am not sure which ones... Impressive definitely for the first one, and I think Poco something for the second? Can you tell that I am not into QHs lol.

I couldn't find where UC Davis has a test for OLWS. Is there another lab that tests for it or did I just miss it on UC Davis's site?

Lethal White Overo - Horse Coat Color

There is the link for you. LWO can be called OWLS, lethal white, frame or just "overo" (although if I could shoot every person who just calls it overo, I happily would...).

I would change your website. He will not pass dun to over 50%. He has a 50% chance of passing dun every breeding. Not more than 50%.

HERDA is traced back to the QH Poco Bueno.
