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

Mexican hairless dogs are heterozygous (Hh) , carrying a single copy of the recessive 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) 20%
B) 14%
C) 10%
D) 39%
E) 46%
