Gce Model Questions Vol1 2025 Biology Question 3
Practice objective / multiple choice question 3 from the 2025 Gce Model Questions Vol1 Biology examination.
In a diploid population with an effective size \(N_e = 500\), the probability that a newly arisen neutral allele becomes fixed is \(1/(2N_e)\). A newly arisen beneficial allele has a selection coefficient \(s = 0.02\). For a large population, the fixation probability of a beneficial allele can be approximated by \(2s\). Calculate the ratio of the fixation probability of the beneficial allele to that of the neutral allele.
