Brindles??

[tussock]

From my understanding brindle in horses is not controlled by a gene. It's the result of twins that in the early stages of existance become one. So say one of the foals is genetically chestnut and the other one is genetically bay but the one foal that is born will be little bit of both (and these horses have two sequences of DNA). I think it's more common in real life but the foals have the same color and hence the brindle pattern isn't viewable. A horse that give foals that shouldn't be possible for him or her genetics is most likely one of these horses.

There is an inheritable form of Brindle in horses. It is currently rare, but it's popping up more and more in certain lines. One type is seasonal, one stays on all year round.

I think the game would first need to have the possibility of twin foals before it could tackle brindle.

Unlike in dogs, where brindle pattern is geneticaly determined, in horses it is an extremely rare result of chimerism: two embryos fusing into oen in the early stages of development. The resulting chimera horse has two different sets of colour genes expressing themselves, resulting in the brindle pattern. Obviously, brindle can never be inherited/passed down to offspring since no colour=related gens influence its apperance.

So without first having a possibility of a mare concieving two embryos at the same time, there should be no way to ever have brindles, if the game wants to stick to real life genetics.

Twins are already possible, but would not be necessary to produce brindles. A random chance of chimerism could be coded into the game, I assume.

There is a form of inheritable brindle.

[WitchWolf]

Hm. Didn't know about twins being possile. Then again, I've only been on here for a day or two thus far.

Also, from what I've been able to find, the only type of inheritable brindle is the IP genetic disorder which I'm guessing is something you'd want to qickly breed out, not breed for.

That last picture is Catch a Bird, a Kiwi stallion It's common enough in Thoroughbreds and Kaimanawas, though it's generally produced by chimerism. Which isn't as rare as you might think.

[MoonRiver130]

Brindles are not always or even mostly chimeras.

This is a misconception brought on by the Catch a Bird case, in which he was likely a chimera that expressed such with an odd white brindle type pattern (and also produced the only true roans in the thoroughbred breed).

Chimeras usually express with patches of color we don't normally see, like black and chestnut paint patterns. True brindle is a wild card so far, although as it's been pointed out people are starting to try and breed for it. Think of it like brindle on dogs. Chimerism and brindle are not connected, it was just chance that Catch a Bird happened to have a brindle like pattern.

both of these horses are chimeras

Regardless I feel like we'll receive white patterns before we get these.

A brindle gene has been found but it also causes the horses to loose their hair. http://equinetapestry.com/2014/04/a-her ... in-horses/

The other way brindle is cased is if the horse is a chimaera (twins that merged at an early stage, it doesn't even have to be twins, sometimes DNA is left over in the uterus from previous young.) It is believed that chimaerism is more likely to happen with duns.

Chimerism is what happens when twins are absorbed, so thats why you get horses with say, black and brown marking, or half thier face is black and half is grey. Nobody knows yet what causes brindle, much like sooty, but it would be an interesting thing to have, although considering its extremely rare I wouldnt want to see it all over the place
