A link to the mares and stallion would help. It is possible that there was a lethal gene interaction that caused a dead foal. Frame (Olw) is always homozygous lethal. Splash 2 (PAX3C70Y) and splash 3 (SPs3) are lethal when homozygous or combined with each other. The kit mutations have various chances of lethality as explained in this post: http://hj2.huntandjump.com/forum/discussion/13757/new-kit-lethality-and-kit-mutation-load-explained#Item_11

I'm going to assume the mix of genes were lethal. But link the horses here and then we can see if there could have definitely been a lethal combination.

He has frame so I'm assuming he was bred to two frame mares. Not ridiculous as it happens in real life and this game mimics real life for the most part!

Yep they also have frame. So that was the issue :)

Can I breed these 2 mares to this brindle?

The game would have told you the foal died when it happened. Make sure you read any messages that pop up. :)

@Starfire you can do this yourself. There is a very helpful chart in this link:
http://hj2.huntandjump.com/forum/discussion/13757/new-kit-lethality-and-kit-mutation-load-explained#Item_11

w20+w20=fine
w20+to=fine.
w2+w20=low risk.
w2+to=fine
I'd go ahead and breed the two.

Thank you for this but I'm not really understanding the chart but will understand it the more I play the game thanks again that was nice :)

Is it saying everything is ok together but kitW and KitW?

Let me step back a bit to give you a bit more of the background information. This is how genes work.

For every gene a living thing has, it will get one copy from its father and one copy from its mother. Both father and mother have two copies of each gene that they got from their parents, and so on back through the generations. This applies to plants as well as animals. In fact, the science of genetics began with a study of pea plants and the peas they produced.

So, for every one of the genes that affect a horse's color or the pattern of its color, every horse has two copies, one from its sire and one from its dam. When sperm cells and egg cells are created, only one copy of each gene goes into each sperm and egg cell. The gene copies the sperm cell has are random, and the same thing happens with the egg. When the two cells come together to form a new foal, the foal gets that random combination of gene copies, one from the stallion and one from the mare.

It's kind of like tossing pennies. Each time you toss the coin, there is a chance that it will land heads up and an equal chance that it will land tails up. This does not mean that if you toss the coin 10 times, it will be heads 5 times and tails 5 times. The chance of either result is the same every time you toss the coin, so you might get a sequence like: 3 heads, 2 tails, 1 head, 1 tail, 1 head, 2 tails. The result of each toss is random.

So there is no way of knowing ahead of time whether the stallion will pass on the gene copy he received from his mother or the gene copy he received from his father. And there is no way of knowing whether the mare will pass on the gene copy she got from her mother or the copy she got from her father. The combination a foal receives is a random group of all the copies of the gene available.

That's what the little chart I posted is showing. What are all the possible pairs of copies of a certain gene that can be created with these two horses and what are the chances that the foal will get a seriously mutated copy from each parent and so will never develop into a living foal.

The Kit gene has developed a lot of mutations over the ages that cause white hair to develop on a horse's body. These mutations break the gene so that it may not be able to perform all the functions it is supposed to. The more the gene is broken, the more white appears on the horse. If a horse has one complete copy of the Kit gene, it will be OK. If it has two copies with mutations, then the gene may be so broken that it can't do its work and the foal dies before it can be born.

I believe that scientists have identified at least 20 mutations of the Kit gene that break the gene so much that two copies will prevent the foal from developing. This is why understanding how the Kit mutations interact is hard to understand.

You are right that the more you play the game, the better you will begin to understand how horse color genetics works. Don't worry if you continue to be puzzled. Just keep asking questions, and we will be glad to keep answering them.

And another reason why I'm having a harder time figuring the charts out and the genes is because I didn't graduate high school or my G.E.D sorry for asking so many questions it's hard for me to understand

I'm glad that my answer helped, Starfire. I like teaching, and it's great to know when I am making something easier to understand. Don't feel bad about having to ask questions. You won't be the first player who has had to keep asking what something means or how it works. Asking questions is the best way to learn, I think.

You are also helping the rest of us by asking, because the very best way to really master something is to try teaching it to someone else. Sometimes when I answer a question, Ammit, the game's creator, has to come along and explain that I got something wrong. I'm glad she does that, because then I get the chance to learn more about this fascinating game.
