Igcse Model Questions Vol1 2020 Biology Question 31
Practice objective / multiple choice question 31 from the 2020 Igcse Model Questions Vol1 Biology examination.
In a population of 2000 beetles the frequency of allele A is 0.6 and allele a is 0.4. Assuming Hardy-Weinberg equilibrium, the genotype frequencies are \(AA = p^{2}\), \(Aa = 2pq\) and \(aa = q^{2}\). A disease kills 30 % of individuals with genotype \(AA\), 10 % of those with genotype \(Aa\) and none of those with genotype \(aa\). After the disease outbreak, what is the new frequency of allele \(A\) among the surviving beetles? Give your answer as a fraction in lowest terms.
