Think about another population of the same flower, but in this case there is another incompletely dominant blue (B) allele in addition to red and white alleles (in this case genotype RB would have a purple phenotype).

What are all the possible genotypes and phenotypes in this population?

If you knew the proportion of the red allele, could you calculate the proportion of the other two alleles?

Symbolically (using p, q, and r) show how you would calculate the genotype and phenotype proportions.
