Who is Gregor Mendel?
Brown eyes are a dominant eye-color allele and blue eyes are recessive. A brown-eyed woman whose father had blue eyes and whose mother had brown eyes marries a brown-eyed man whose parents are also brown-eyed. They have a son who is blue-eyed. Draw a pedigree (info above) showing all four grandparents, the two parents, and the son. Indicate each individuals' possible genotypes.
