Answer 1

Answer:

woman dd, man Dd

Explanation:

Polydactyly is a dominant trait that results in extra fingers and toes in humans. A man with polydactyly marries a woman with 10 fingers and toes. They have a child that has a normal number of digits. The phenotype of the man's father is unknown, but his mother has a normal phenotype. What are the genotypes of the married couple? (D = polydactyly allele; d = wild type allele)
