There is an autosomal gene that controls baldness, and its expression is sex-influenced. The gene for
baldness (B) is dominant in males but recessive in females. In females, the allele B1 for nonbaldness is
dominant over the gene for baldness. If heterozygous, nonbald woman marries a nonbald man, what
will be the appearance of their children? Work out the possibilities for each sex. What will be an ideal response?
BB1 ? B1B1 ? BB1 + B1B1; all daughters nonbald, 1/2 sons bald, 1/2 sons nonbald
