Question

You meet a man on the street. He has 10 fingers and 10 toes. What is his genotype with respect to the polydactyly trait

Answer 1

woman dd, man Dd

Step-by-step 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)
