3. Construct a pedigree chart by following the information given below. A man who is heterozygous for an autosomal dominant trait marries a woman who is unaffected by that trait. Suppose they have 5 children in this order: affected son, únaffected son, affected daughter, unaffected son and unaffected daughter. The youngest daughter married a man who does not carry the gene for the trait. They have 2 children, one boy and one girl The eldest child of the generation I couple, on the other hand, married a woman who also exhibits the trait. They have 3 children, 2 girls and 1 boy, all of whom show the trait. What are the genotypes of
