A nucleotide site is polymorphic with C and G in a plantspecies. Currently, there are 80, 240 and 180 individual plants with CC, CG, and GG genotypes, respectively, in the entire population.

1. What is the frequency of allele G in the current generation?

2. If mating (pollination) occurs randomly among plants and plants with different genotypes are equally fit, what is the expected frequency of CG heterozygotes in the next generation?
