(homozygous dominant, homozygous recessive, heterozygous) III-3: nn-homozygous recessive 1. Is this trait dominant or recessive? Explain your answer.
2. How can you know for sure that individuals II-3 and II-4 are heterozygous?
3. 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. Please draw a pedigree showing all four grandparents, the two parents, and the son. Indicate which individuals you are certain of their genotype and where there are more than one possibilities.
