The Hardy-Weinberg equation is a mathematical expression that can be used to calculate the genetic variation of a population at equilibrium.

Evolution is constantly at work, making it impossible for the frequencies of a population's alleles and genotypes to remain constant through time. What are the 5 principles of the Hardy-Weinberg equilibrium? (1) No natural selection -- organisms will not adapt to environmental changes by ...
Hardy-Weinberg Equilibrium (HWE) is used to estimate the number of homozygous and heterozygous variant carriers based on its allele frequency in populations that are not evolving. Previously, deviation from HWE in large population databases were investigated to detect genotyping errors, which can result...

Bayesian test procedures for Hardy–Weinberg equilibrium for the autosomes have been described, but Bayesian work on the X chromosome in this context is lacking. This paper gives the first Bayesian approach for testing Hardy–Weinberg equilibrium with biallelic markers at the X chromosome. Marginal ...
Once we know our population is in Hardy Weinberg equilibrium, and therefore that it is nonevolving in terms of the gene in question, we are ready to compare it to another population for that locus. If it is not in Hardy Weinberg equilibrium, there may be natural selection or nonrandom mat...
Typically Hardy–Weinberg equilibrium is tested in unrelated individuals using a v2 goodness-of-fit test that compares expected and observed numbers of heterozygotes and homozygotes. In this report, we propose a likelihood ratio test for Hardy –Weinberg equilibrium that accommodates a mixture of ...
