Male-pattern baldness is an example of a sex-influenced trait. The baldness allele, which causes hair loss, is influenced by the hormones testosterone and dihydrotestosterone, but only when levels of the two hormones are high. In general, males have much higher levels of these hormones than females, so the baldness allele has a stronger effect in males than in females. (B-baldness; N-full or normal) hair) A normal man marries a normal woman. What can be the possible genotypes of the parents respectively? * a. BN x BN b. NN x BN c. NN x bb d. NN x BB e. BN x bb f. BB x BB
