Given a population with the following proportions of each genotype - 0.11 homozygote dominant individuals, O.21 heterozygotes, determine the total frequency of dominant alleles in the population.
Hardy Weinberg principle is considered one of the cornerstones of population genetics. The group of individuals who can interbreed termed as a population. The gene pool is part of the population. It consists of genes and alleles of the members of a population. Hardy Weinberg principle provides a model that expresses the frequency of alleles and genotypes of a population with infinite size. According to this principle, random mating takes place in the population, which allows the determination of genotype frequencies using allele frequency. Gene flow never introduces new alleles. The frequency of alleles remains the same over time. Hardy-Weinberg explains that allelic frequency in a population can be maintained, but the population should fulfill some criteria. Such as, there should be random mating, no mutation, large size population, no selection, etc. Hardy-Weinberg proposes the mathematical equation to calculate the allelic and genotypic frequency.
