Hardy-Weinberg law: The Hardy-Weinberg law is also referred to as the hereditary equilibrium law or genetic equilibrium law. The basis of the Hardy-Weinberg law is as follows: in an infinite, randomly mating group, when there is no migration, mutation, selection, or genetic drift, the genotype frequency and gene frequency at a locus in the group will remain unchanged generation by generation, achieving a genetic equilibrium state, known as the Hardy-Weinberg equilibrium. This law was proposed by G.H. Hardy, a British mathematician, and W. Weinberg, a German medical scientist, in 1908.The factors that influence the Hardy-Weinberg equilibrium are as follows:1. Mutation: Under natural conditions, the rate of gene mutation caused by the reparation effects of DNA replicase is 1×10 -6 -10 -8 /gamete/locus/generation in higher animals, demonstrating that the frequency of natural mutation is very low.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
