So, the foal inherited to much of both genes? Which killed it?

What did that mare had as WF, and what was the foal like?

I would presume that a high WF killed the foal. Splash and frame and w20 (I think on the last one) increase WF. The foal would've needed to have the highest wf for that combo which is 105 and, while rare, it does happen. Just bad luck.

KitW20 and KitW2 are lethal together when the foal has extensive white factor. It probably got both as well as Splash, which would increase the white factor. Very unlucky! It won't happen every time you make this cross, but it is (obviously) a risk you would take with these two horses.

Here's a link to a post that explains kit lethality. I've saved the full lethality chart with the numbers (linked at the bottom of the post) to my computer and consult it very often, as it's more in depth, but bookmarking this link would be just as good.

I suggest you give it a good look over before you try any risky crosses!

That foal got lucky and didn't inherit any Kit genes, therefore had nothing lethal, genetically.

Every time you breed, you won't always get the same genetic outcome in the foal. Each horse has two options for each gene, and every foal is a gamble as to which of the two it will get.

So do I just not breed these mares or? Gamble if its a rare thing to happen?

I breed for colour which means all my horses have KitW genes of sorts. Is this just a bad line to breed in?

Good thing to look out for
