How to solve questions for the Harding-Weinberg Equilibrium problems. This is not one of problems its a sample. Please explain this to me. 27.9% had red flowers with the genotype RR. 49.9% had pink flowers with the genotype Rr. 22.5% had white flowers with the genotype rr. How do you determine the allelic frequency, expected genotype frequency if the population were all genetic equilibrium, and compare the calculated expected genotypic frequencies.
