What color horse would you get if you bred a dun colored horse to a golden palomino?

Answer 1

Dun can be red dun, blue dun or dun.

If we assume that the dun is A-Dndn or A-DnDn

We know the palomino is --eeCrcr

50% of the foals have the Crème allele and therefore be dilute.

50% of the foals (if the Dun parent is heterozygous Dndn) will

have the Dun allele.

If the dun parent is homozygous dun DnDn all foals produced will be dun.

If the Dun horse is A-Dndn and Ee at the extension site.

50% of the foals will be red based. This could be chestnut, red dun, dunalino (palomino and dun),

50% will be non-red. This could be bay, dun, dunskin (dun and buckskin)

If the Dun horse is A-DnDn and Ee at the extension site.

50% of the foals will be red dun or dunalino

50% of the foals will be dun or dunskin.

If both the stallion and the mare carry the true black allele a there is

the possibility that a resulting foal could be a grulla or a crème dilute grulla.

If either or both of the parents are color tested, the percentages would be

simple to calculate.

Examination of the parents, grandparents and any offspring produced would

shed light on what the true possibilities are for this mating.

Answer 2

If the hose is a true white. You have 50% chance of having a white foal. True white horses are always heterozygous Ww.
