In a second forest sample, downwind from the industrial centre, 300 moths were trapped. Of these, 210 were dark coloured and the rest were light. Dark is dominant to light. a) Use the HWP to calculate the frequency of the dark and light allele in the area up wind from the industrial centre. b) Use the HWP to calculate the frequency of the dark and light allele in the area down wind form the industrial centre. c) Suggest reasons to account for these differences in allele frequencies?
