Igcse Model Questions Vol1 2020 Biology Question 32
Practice objective / multiple choice question 32 from the 2020 Igcse Model Questions Vol1 Biology examination.
A bacterial population initially contains 10 000 cells. A mutation that confers resistance to an antibiotic is present in a single cell, giving an initial frequency \(p_{0}=0.001\). Resistant cells reproduce at a rate 1.5 times that of non‑resistant cells each generation, while non‑resistant cells reproduce at a rate of 1. The population has discrete generations and no back‑mutation. After how many generations will the frequency of the resistant allele exceed 0.5? Give the smallest integer number of generations.
