What coat color can you get out of a chestnut mare and palomino horse?

You can get a variety of coat colors from a chestnut mare and a palomino horse! Here's a breakdown of the possibilities:

Chestnut Mare:

* Genotype: eeAA or eeAa (always carries the recessive "a" allele for chestnut)

Palomino Horse:

* Genotype: ee*CrCr (carries the cream gene "Cr" which dilutes the base color)

Possible Offspring:

* Chestnut: eeAA or eeAa (If the palomino passes on the "a" allele for chestnut)

* Palomino: ee*CrCr (If the palomino passes on the cream gene "Cr")

* Dun: ee*CrA or ee*CrA (If the palomino passes on the cream gene and the mare passes on the "A" allele for bay)

Important Notes:

* The "e" allele is always present in both the chestnut mare and the palomino, so the offspring will always have a "ee" genotype, resulting in a base coat color of either chestnut or bay.

* The palomino carries two "Cr" alleles, which means they will always pass on the cream dilution.

* The mare can either pass on the "A" allele for bay or the "a" allele for chestnut.
