You score these animals for the R locus and find that this locus has two alleles, R (dominant) and r (recessive). 3200 individuals are homozygous dominant, 1,600 are heterozygous, and 200 are homozygous recessive. a) Calculate the allele frequencies for this population. Show your work. b) Calculate the observed genotypic frequencies for this population. Show your work. c) Calculate the expected genotype frequencies if the population is in Hardy-Weinberg equilibrium. Show your work. d) Does this population appear to be at H-W equilibrium? Why or why not? (You do not need to analyze this statistically).Assume you have a population with alleles A and a at a genetic locus.
