If a homozygous white horse CWCW and a homozygous black horse CBC® are bred together, what is the likelihood that their offspring will be roan with both colors represented in their hair if this gene follows a codominant inheritance pattern? (1 point)

Answer 1

In this scenario, let's analyze the genetics involved. The homozygous white horse has the genotype CWCW, and the homozygous black horse has the genotype CBCB.

When these two horses are bred, the offspring will all inherit one allele from each parent:

• From the white horse (CWCW), the offspring will always inherit CWC (the allele for white).
• From the black horse (CBCB), the offspring will always inherit CBC (the allele for black).

Thus, all offspring will have the genotype CWCBC.

Since the C allele (white) and the C allele (black) are codominant, the phenotype for the offspring will express both colors. This means the offspring will be roan, exhibiting a mixture of both white and black hairs.

So, the likelihood that their offspring will be roan is 100%.
