If a homozygous white horse WCW and a homozygous black horse C®c® 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, we have two homozygous horses: a homozygous white horse (WCW) and a homozygous black horse (C®c®).

When these horses are bred together, we can set up a simple Punnett square to determine the possible genotypes of their offspring. The white horse genotype is WCW, and the black horse genotype is C®c®.

The offspring will receive one allele from each parent:

• From the white horse (WCW), the offspring can only inherit WC (the white allele).
• From the black horse (C®c®), the offspring can inherit either C® or c® (the black alleles).

Thus, the possible genotypes for the offspring can be:

1. WC C® (which would be a roan horse).
2. WC c® (which would also result in a roan horse).

Since both offspring genotypes include the white coat color allele and one black coat color allele, they will exhibit the roan phenotype.

Since both possible genotypes for the offspring will be roan, the likelihood that their offspring will be roan is 100%.

So, the answer is: 100%
