percentage of the offspring will be roan and express both colors in their hair? (1 point)
O 50 percent
O 25 percent
O 100 percent
O 0 percent

Answer 1

When breeding a homozygous white horse and a homozygous black horse, there is a 0 percent chance of producing roan offspring.

Step-by-step explanation:

The answer is 0 percent.

When a homozygous white horse and a homozygous black horse are bred together, their offspring will not be roan and express both colors in their hair. This is because the trait for roan coloration is determined by a different gene, and neither of the parent horses possess the gene for roan coloration. Therefore, all the offspring will inherit either the white or black color gene, resulting in a 0 percent chance of roan offspring.
