Question

In a randomly mating laboratory population of Drosophila, 4 per cent of the flies have black bodies (black is autosomal recessive, b) and 96 per cent have brown bodies (normal colour, B). If this population is assumed to be in Hardy-Weinberg equilibrium, what are the allelic frequencies of B and b, and the genotypic frequencies of BB and Bb?

To solve this problem, we can use the Hardy-Weinberg equilibrium equations. The Hardy-Weinberg equilibrium describes the distribution of alleles in a population that is not evolving. It is based on the assumption of random mating, no migration, no selection, no mutation, and a large population size. The equations for the Hardy-Weinberg equilibrium are as follows:
