Imagine a population of a flower species, where there are two types of individuals, PINK-petalled flowers, and RED-petalled flowers. The petal color in this population has been shown to be controlled by a single gene, with alleles A and B (parent generation with a 50/50 frequency of alleles A and B). If an adult individual has AA or AB genotype¸ they have PINK petals, but if they have the BB genotype, they have RED petals. After 10 generations, the genotypes for 1000 plants were measured and 300 of the 1000 plants were of type AA, 300 of the 1000 plants were genotype AB, and 400 of the 1000 plants were of type BB.

1. What is the frequency of the A and B alleles in this population?

2. Is this population in Hardy-Weinberg equilibrium? Explain why or why not in 2-3 sentences.

3. What fraction of the flowers have RED petals in the measured population? What fraction of plants would you expect to have RED petals if the population was in Hardy-Weinberg equilibrium?
