Gce Model Questions Vol1 2021 Biology Question 10
Practice objective / multiple choice question 10 from the 2021 Gce Model Questions Vol1 Biology examination.
In a diploid population with effective size \(N_e = 10{,}000\), a new advantageous allele arises with selection coefficient \(s = 0.01\) (heterozygote fitness \(1+s\)). Using the approximation \(P_{\text{fix}} \approx 2s\) for a beneficial allele, estimate the probability that this allele will become fixed. Compare this to the neutral fixation probability \(1/(2N_e)\) and state how many times larger the advantageous probability is.
