Perlino Foal

What CM said. A double cream
What CM said. A double cream horse can only pass on one cream gene to offspring, never both. You could get a buckskin, smoky black, or palomino from breeding her to a perlino (with no other knowledge of their genetics besides face value of their color).
If there are other genetic factors at work:
If either the mare or stud are homozygous black, you can only have smoky cream or buckskin foals.
If either the mare or stud are homozygous agouti (the bay gene) you can only have buckskin or palomino foals.
If either the mare and/or stud are homozygous black and homozygous agouti, you can only have buckskins.
Really? My neighbor has a
Really? My neighbor has a buckskin stallion and they bread their bay mare to him and got a perlino. thats why i was wondering what the chances of that happening again are. Also, I understood that bays do cary one cream gene. I read that a bay horse is a black horse that recieved one cream gene so the black only stayed at the horses "points" and that a palomino is a red horse that recieved one cream gene or single dilute. Is all of this info that I recieved wrong? and if so, how in the world did my neighbors get that baby out of those two color combos??
You're right about palomino.
You're right about palomino. But a bay horse is a black horse that has a dominant agouti gene. You can read about bay here, on our "Beginning Genetics" page - http://colorgenetics.info/equine/conten… - and about cream on our "Dilutions" page - http://colorgenetics.info/equine/conten…
As for your neighbor's perlino foal, there could be a couple of different scenarios that could have happened:
A) Foal is not perlino; he might not be a double dilute at all; sometimes single dilutes can be mistaken for double dilutes and vice versa;
B) The sire is not the sire, or the dam is not the dam. Being the "wrong" color is often a sign something might have gone wrong in the breeding shed, something accidental happened, etc.
C) The dam is not bay, but actually buckskin. That happens too.
D) They have a double dilute foal but not a double dilute cream foal; instead, sire or dam may carry a hidden dilute gene, like pearl, and this has combined with cream to create a pseudo-perlino foal.
E) They have a de novo mutation; extremely unlikely, but cannot be ruled out
The easiest way to figure it out is to DNA type the foal to sire and dam. If that checks out, then you color test the foal, then the dam, and then the sire.
*Or something else is going on I can't figure out.
With a bay mare you can never
With a bay mare you can never have a perlino, cremello or smokey cream foal. Even if crossed to one of those, you can only get a single dilute foal because your mare does not carry cream, and a perlino requires two cream genes, one from each parent.
