Problem:
The M allele is at a frequency of 0.2 in a population of 500 west-slope cutthroat trout from Rock Creek that is in Hardy-Weinberg proportions. An outbreak of whirling disease kills 30% of the individuals with the MM genotype, but none of the other fish (i.e., mm or Mm fish)
Required:
Question 1: What is the frequency of each genotype before the disease outbreak?
Question 2: Based on these data, what are the fitnesses of each genotype and what is the mean fitness of the population?
Question 3: What is the frequency of each genotype after the disease outbreak?
Please read all the questions carefully and answer them.
