Estimate the frequency of dominant allele.?

Industrial melanism refers to the dark pigmentation that evolved in some insects, giving them protective coloration on vegetation darkened by soot in industrialized areas prior to smokestack filtration. In one area near england in 1956, 87 % of moths had black bodies due to carrying the dominant autosomal allele for melanism. uming random mating, estimate the frequency of the dominant allele and the frequency of melanics that are heterozygous.
