Pattern baldness is caused by a dominant autosomal allele. Epistasis is involved in this gene’s expression, however. The pattern baldness gene is only expressed when significant amounts of the male hormone testosterone are present. A woman whose father was not bald married a man with a full head o’ hair. They have a son who develops pattern baldness.

What was mom’s genotype?

Dad’s genotype?

What is the likelihood that their daughter’s will develop pattern baldness?

please help. thanks.
