Hardy-Weinberg Principle

Hardy-Weinberg Principle. Hardy-Weinberg - original proportions of genotypes in a population will remain constant from generation to generation Sexual reproduction (meiosis and fertilization) alone will not change allelic (genotypic) proportions. Hardy-Weinberg Equilibrium.

10. Genetic variation and fitness

10. Genetic variation and fitness. Hardy Weinberg law. According to the Hardy Weinberg law gene frequencies are constant. How can evolution occur?. Assume a gene with two alleles A and B that occur with frequency p and q = 1-p. Assumptions of the Hardy Weinberg law
