50 percent
are u sure
I apologize for the incorrect response. The correct answer is 50 percent. If one parent is heterozygous for dimples (Dd) and the other parent does not have dimples (dd), their possible genotypes would be Dd and dd. In this case, there is a 50 percent chance that the child will inherit the dominant allele (D) and have dimples, and a 50 percent chance that the child will inherit the recessive allele (d) and not have dimples.

If a homozygous white horse (WW) and a homozygous black horse (BB) are bred together, all of the offspring will be black (Bb) because black is dominant over white. Therefore, the percentage of offspring that will be roan and express both colors in their hair is 0 percent.
