Suppose a population is carrying a condition controlled by two alleles: r (dominant) and r (recessive). if the frequency of the r allele is 15%, and the frequency of the r allele is 85%, what will be the frequency of the rr genotype, assuming evolution is not occurring?

not the best question format lol but what i think might as scale color is controlled by a single gene with two alleles, the green allele and the yellow allele. when moths that are homozygous for green scales are mated with moths that are homozygous for yellow scales, 100% of the offspring have green scales.

what is this saying?
