There are three alleles at a gene determining eye color in a population of wild cats, the B allele (brown eyes) is dominant to both the G allele (green eyes) and the Y allele (yellow eyes). The G allele is dominant to the Y allele. In a population of 1000, there are 100 yellow-eyed cats, 400 green-eyed cats, and 500 brown-eyed cats. What is the expected frequency of the Y allele?

In a population of 1000, there are 100
yellow-eyed cats, 400 green-eyed cats, and
500 brown-eyed cats. What is the expected
frequency of the Y allele?
