Question: In wild petunias, the allele for red flower color (R) is dominant over the allele for white flower color (r).  We sample a population and find 225 plants have white flowers and seventy-five have red flowers. If the population is in HWE, what are the allele frequencies of R and r in this population? How many of the 75 plants that have red flowers are homozygous and how many are heterozygous at the flower color locus?
