The trait for male-pattern baldness is a recessive traitencoded for by the letter “b.” Non-baldning is encoded for bya dominant allele encoded for by the letter “B.” A street surveyconducted by Hair Club for Men foud that out of 1,000 men: 360 hadmale pattern baldness, the other 480 had non-balding andwere heterzygous, and 160 who non-balding and werehomozygous.

a.) Using the information, find the allele frequencies for “B”and “b.”

b.) What are the expected genotype frequencies?
