Well, the sire's a silver dapple/silver black with one tiger eye gene from his sire. The paternal granddam is a palomino, so the dad could have gotten a hidden cream gene. The dam is a greying chestnut. It's been a while and I can't tell if there's dun there or if the greying has the body paler than the legs in the dam's foal picture. She has one tiger eye gene from her dam. I don't think there's hidden agouti (bay) genes in the dam, but then I didn't look back too far to really tell.

If your lucky the foal might get both tiger eye genes from the parents and have bright eyes. This is very unlikely, though, and it's more likely your foal will only end up with one gene. I believe it's a 25% chance to get no genes, 50% to get one gene, and 25% to get both.

It mostly likely won't be bay. You'll have either a chestnut or black base. It's 50/50; the father only has one gene I believe so it's not a guarantee that you'll get black.

If the sire has a cream gene then you might have a palomino or smoky black. I'd say this might not be a high chance; it's a 25% chance the dad got it from his palomino parent, and if he did then it's another 25% chance the foal will have it. I'd say probably not, but you never know.

If the sire passes down silver then you might have a silver dapple; silver doesn't show on chestnut bases. I'm going to guess that the father only has one silver gene, but as silver doesn't show on chestnut I can't be sure that his non-silver presenting parent doesn't have the gene and didn't pass it down. I'm not looking too far into ancestry so we'll say that the father only has one gene, making it a 25% chance for the foal to get it.

If the dam passes down grey then you'll ultimately end up with a grey. The mom only has one gene so it's not guaranteed to be passed down. This'll be another 25% chance.

I'm going to guess plain black, because I quite like black horses. I'm also going to say one tiger eye gene.

In total probability, your foal will likely have one tiger eye gene, be either black or chestnut, and have a low chance to be silver dapple like the father or plain chestnut as silver doesn't show, or go grey.

I think I got all of that right but if anyone notices I messed something up let me know. :)

»IR« Cascading Lies is a silver smoky black blanket (with heterozygous tiger eye). If you compare his foal photos with those of his dam, you'll see that Cascading Lies has a slightly colder colour than his dam- smoky black foals have a colder tone than normal black foals.

»IR« Nightmare Daydream is a grey on red dun near leopard (with heterozygous tiger eye). You can tell that she's red dun and not chestnut because, in her foal pictures, her mane, tail, legs, face and belly are several shades darker than the rest of her.

With dominant genes, if one parent has one copy of the gene, there is a 50% chance of the foal inheriting it, not 25%; thus the foal has a 50% chance of being a single cream and a 50% chance of inheriting silver dapple (based on the assumption that the sire is heterozygous.) Since tiger eye is recessive and both parents carry one copy, there is a 25% chance of the foal being tiger eye (Tg/Tg), 50% of the foal carrying tiger eye (Tg/tg) and 25% chance of the foal having no tiger eye (tg/tg).

In summary, the foal could be:
  • E/e or e/e (black or chestnut)

    a/a or At/a or A/a or A+/a (no bay (I suspect this will be the case, however the other options are still possibilities due to long lines of chestnut based horses), seal brown, bay, wild bay)

    Cr/cr or cr/cr (one cream or no cream)

    Tg/Tg or Tg/tg or tg/tg (tiger eye or no tiger eye)

    Z/z or z/z (silver or no silver)

    G/g or g/g (grey or no grey)

    D/d or d/d (dun or no dun)

    Lp/Lp or Lp/lp or lp/lp (homozygous varnish roan, heterozygous varnish roan, no varnish roan, a black based horse will have less extensive patterning than a chestnut.)

That looks like a Chestnut Near Leopard.

She could be a Red Dun Near Leopard but we'll be able to tell more accurately when she's older.
