Question

Suppose there is a population of plants in which there is an incompletely dominant red allele (R) and a recessive white allele (r). Homozygous RR plants have red flowers, heterozygous Rr plants have pink flowers, and homozygous rr plants have white flowers. Also suppose there are 400 red-flowered plants, 200 pink-flowered plants, and 400 white-flowered plants. (a) What are the frequencies of each of the alleles? Show your work. (b) Is the population described above at Hardy-Weinberg equilibrium? How can you tell? This will require calculations. Show your work.
