Hitchhiker’s thumb is an autosomal recessive trait determined by a single gene with two alleles, H and h. Suppose the allele frequencies in a population are f(H) = 0.8 and f(h) = 0.2.

Which combination(s) of genotype frequencies is/are possible in this population if it is in Hardy-Weinberg equilibrium? List all that are possible.

Group of answer choices

f(HH) = 0.6, f(Hh) = 0.2, f(hh) = 0.2

f(HH) = 0.64, f(Hh) = 0.32, f(hh) = 0.04

f(HH) = 0.7, f(Hh) = 0.2, f(hh) = 0.1

f(HH) = 0.6, f(Hh) = 0.4, f(hh) = 0

f(HH) = 0.8, f(Hh) = 0, f(hh) = 0.2
