In Drosophila melanogaster, wing shape is an autosomal trait. Vestigal wing is recessive (v) to the dominant trait for the normal long wings (V). In a mainland source population, the allele frequency of v is 0.02 . A small, experimental population of 100 flies was introduced on an island and had 20 flies with vestigal wings and 40 heterozygotes. What are the allele frequencies of V and v in this introduced population? What proportion (%) of heterozygotes and homozygous recessive flies would you expect to see after a few generations of mating on this island? What phenomenon of population genetics does this experiment demonstrate? p+q=l, p^2+ 2pq + q^2 = 1

I just need the last part. The % calculation of proportion of heterozygotes and homozygous recessive flies after a few generation. Thanks
