The frequency of a recessive allele, r, was measured in a population of insects over ten generations after a new pesticide was introduced. The graph shows the results.
Describe how the frequency of allele r changes over the ten generations.
Deduce whether this population is in Hardy-Weinberg equilibrium for this gene. Give a reason for your answer.
Suggest which Hardy-Weinberg condition is not being met in this population.
