Mexican Hairless Dogs Are Heterozygous (Hh), Carrying a Single Copy

Mexican hairless dogs are heterozygous (Hh) , carrying a single copy of the lethal allele. In a given population, the Hh genotypic frequency is 60% and the frequency of each homozygote is 20%. Assuming w = 1 for the Hh and hh dogs, what is the estimated genotypic frequency of the lethal HH genotype after reproduction?

A) 46%
B) 10%
C) 14%
D) 39%
E) 20%
