Part a in humans, male-pattern baldness may be assumed to be controlled by an autosomal gene that occurs in two allelic forms. allele b determines nonbaldness, and allele b determines pattern baldness. in males, because of the presence of testosterone, allele b is dominant over b. if a man and woman both with genotype bb have a son, what is the chance that he will eventually be bald?
