Suppose that pattern baldness is caused by a single autosomal gene mutation that has
a dominant effect in males (either one or two copies of the mutation cause pattern
baldness) and a recessive effect in females (two copies of the mutation cause pattern
baldness). A second gene on a different autosomal chromosome affects hair color with
a recessive mutation that results in light hair instead of dark hair. Mary has no pattern
baldness and dark hair. Her mother had pattern baldness and dark hair and her father
had no pattern bladness and light hair. Mary marries John who has no pattern baldness
and light hair.
Question: If a son is born to the couple what is the probability that he has
pattern baldness and dark hair like his maternal grandmother?
Question: If a son is born to the couple what is the probability that he has
no pattern baldness and light hair like his father?
Question 11: If a daughter is born to the couple what is the probability that
she has no pattern baldness and light hair?
