In the given problem, the trait (pea color) is determined to have only 2 characters: a dominant allele and a recessive allele. These allele frequencies can be used to compute for possible variations in genotypic frequencies: homozygous dominant YY, heterozygous Yy, and homozygous recessive yy.
Suppose pea color is determined by 2 alleles: the Y allele is yellow and is dominant over the y allele which is green. If the Y allele is found at a 0.9 frequency in a population, what is the frequency of the y allele in that population?
