3) Caucasian humans have a gene which determines the curliness of hair. Individuals with straight hair are homozygous for the straight allele while those with curly hair are homozygous for the curly allele. Heterozygotes have wavy hair.
a) If two wavy haired people mate, what phenotypes and genotypes would you expect among their offspring?
b) If ALL of the many children of another couple have wavy hair, what would the most likely genotypes of the parents be?
