Waec Model Questions Vol1 2021 Biology Question 49
Practice objective / multiple choice question 49 from the 2021 Waec Model Questions Vol1 Biology examination.
In a beetle population, allele A (dominant) gives a bright colour, while allele a (recessive) gives a dull colour. Initially, the frequency of allele A is p = 0.60. After one generation of selection, the proportion of bright beetles (genotypes AA or Aa) rises to 0.92. Assuming random mating and that selection acts only on the dull phenotype (aa) with fitness 1 - s, calculate the selection coefficient s against the dull phenotype.
