Gce Model Questions Vol1 2025 Biology Question 49
Practice objective / multiple choice question 49 from the 2025 Gce Model Questions Vol1 Biology examination.
In a beetle population two alleles \( A \) and \( a \) determine colour: genotypes \( AA \) and \( Aa \) are green, \( aa \) are brown. Initial allele frequencies are \( p = 0.6 \) for \( A \) and \( q = 0.4 \) for \( a \). Brown beetles have 20 % lower survival to reproductive age than green beetles (fitnesses: \( w_{AA}=w_{Aa}=1,\ w_{aa}=0.8 \)). Assuming random mating and selection occurring after reproduction, calculate the allele frequencies \( p' \) and \( q' \) in the next generation (to three decimal places).
