Gce Model Questions Vol1 2020 Biology Question 25
Practice objective / multiple choice question 25 from the 2020 Gce Model Questions Vol1 Biology examination.
In a beetle population the allele G (green) has an initial frequency \(p_{0}=0.60\). After five generations of random mating the observed frequency is \(p_{5}=0.48\). Assuming the change is caused solely by genetic drift, estimate the effective population size \(N_{e}\) using the drift variance formula \(\operatorname{Var}(p)=\frac{p(1-p)}{2N_{e}}\) per generation. Approximate \(N_{e}\) by treating the observed change (\(\Delta p = 0.12\)) as one standard deviation after five generations.
