Answer 1

In a scenario where a homozygous white horse (CWCW) is bred with a homozygous black horse (CBCB) and the gene exhibits codominance, the offspring will inherit one allele from each parent.

The possible genotypes for the offspring would be:

• From the white horse: CW (white allele)
• From the black horse: CB (black allele)

Each offspring will therefore have the genotype CBCW.

Since the alleles are codominant, the phenotype of the offspring will display both colors. This means that the offspring will be roan, having both black and white hairs.

Given that all offspring will have the genotype CBCW, they will all exhibit the roan phenotype. Therefore, the likelihood that their offspring will be roan is:

100%.
