I thought it best for my question to create a different thread than put it into the Generic Wild Bay /Brown and natural shine thread, so it wouldn't muddle up the information there.

So I created one of the new browns:

Then I bred her to one of my old silver browns (as I too breed for them, here on HJ2) and got this foal:

Now what has me confused, is that both got the At gene, and both only have one sty gene, yet she is considered brown, and he is called bay. Is it because I used an old stud? Or is there other factors involved that we don't see. Because I need to know how to breed for the silver brown too, just like LookingGlass.

More or less what would we need to see on the genetics test to make sure that the horse is "brown" based and not "bay" based on the name?

At is recessive to A

That stallion is AA so he can't sire any recessive AtAt or At Aa foals.

Ok, so an AtAt based horse would list as a "brown" on the gene testing name?

Oh, and I had to post this guy I just created, as he is extreemly perfect looking brown, but is also considered a bay, lol. Gonna have to get used to a whole new thing. He is listed as bay, because he has no At gene, but because he is sty sty, he is very dark. (Just trying to get the feel of the change).

This is actually covered in the post At Aa and any amount of sooty or AtAt and 1 or more dose of sooty. The look of horse you posted is a psudo brown. Not genetically brown but just dark.

I'm a little confused now about the difference between/effect of Aa vs AA. I think I get the At stuff.

Never mind, I get it.. those are the two old A and a genes, unchanged..... right?

PurpleSage · Sep 13, 2014 8:52 PM

The sire would have to be Aa in order for there to be a chance of getting a brown foal. :)

Ammit · Sep 14, 2014 3:54 AM

The sire can create psudo browns that look brown but are not called brown with no issue.

ok, after a few days of looking at the genes, I just got to clear my idea out. The Wild bay gene will never transfer over to a brown horse from what I can tell, as to have a brown you need: At a plus sty, so A+At will only get you a wild bay (even with sty), since they are both large A's, and the + and t are only attached to the large A gene. So there is no such horse as "Wild brown".

SandycreekFarm · Sep 22, 2014 6:43 PM

Ammit's first post about these new genes said that A+ (Wild Bay), is dominant over every other bay allele, and At is recessive to everything else. So a horse that has both A+ and At will be wild bay because A+ is the dominant allele of the pair. So yes, there is no "wild brown."

On the other hand, Ata horses can be brown without sooty. http://hj2.huntandjump.com/horse.php?horseid=141980 is a case in point.
