WebIt is a conceptual idea of population equilibrium that was developed by 2 scientists G.H. Hardy and William Weinberg, who suggested some assumptions for stable, non evolving population in which "allele frequencies do not change and therefore evolution does not occur". theses assumptions are : 1. No mutation. WebJan 15, 2024 · To analyze the allele frequency in a population, scientists use the Hardy-Weinberg (HW) equation. The Hardy-Weinberg equation is written as follows: 1 = p2 + 2pq + q2. P and q each represent the allele … WebTo calculate the ratio p: q after selection this ratio has to be normalised to make p + q =1. To do this, the average fitness, w, is calculated. ...
