Solution
To solve this problem, we need to create a Punnett square. The Punnett square is a square diagram that is used to predict the genotypes of a particular cross or breeding experiment.
The bay stallion has a genotype of BBCC (since it only has the bay allele) and the buckskin mare has a genotype of BCCC (since it has one bay and one cream allele).
The Punnett square would look like this:
| BC | BC | |
|---|---|---|
| BC | BBC | BCC |
| BC | BBC | BCC |
From the Punnett square, we can see that all of the possible offspring would have one bay allele and one cream allele, meaning they would all be buckskin.
So, the correct answer is 100% buckskin; 0% bay.

Palomino (golden brown) horses are bred for their coat coloration. A breeder will achieve 100% Palomino offspring by crossing a chestnut (dark brown) horse with a cremello (cream) horse. However, if a breeder crosses two Palomino horses, only 50% of the offspring will be Palomino, while 25% will be chestnut and 25% will be cremello. Genetic inheritance of coat color in these horses is best described as:A.codominance.B.complete dominance.C.variable expressivity.D.incomplete dominance.
