The palomino horse is golden in color.Unfortunately for horse fanciers,palominos don't breed true. In a series of matings between palominos,the following offspring were obtained:65 palominos,32 cream-colored,34 chestnut.
What is the probable mode of inheritance of palomino coloration?Do the palomino cross to prove the correct answer to previous question.

Here's a hint (well, OK it's actually pretty broad for a hint):
take 2 alleles that can represent the 'coat-color' gene, call one C for Chestnut and one c for cream-colored. Each chromosome in a pair can have one or the other.
Suppose palominos are genetically Cc (one chromosome has a C allele and the other in the pair has a c allele). If 2 palominos mate, what are the resulting offspring allele combinations?

you may be dealing with genetic co-dominance, where the golden palomino is actually a blend of cream and chestnut coloured hairs.
