Question

Baldness(HB) is dominant in males but recessive in females. The normal gene (Hn)

is dominant in females, but is recessive in males. Explain how a bald offspring can be produced from the mating of normal female with a normal male. Could these parents ever produce a bald girl? Explain.

Answer 1

If the female parent has the genotype BB, all of the offspring will have brown bodies (Figure 9, Outcome 1). If the female parent has the genotype Bb, 50% of the offspring will have brown bodies and 50% of the offspring will have black bodies
