Question

Define hardy weinberg law. mention its significance.

Answer 1

Hardy weinberg law states that small population have less rando.ness and large population have more randomness and they abolish quickly .to measure population in a area hardy weinberg law is applicable

Answer 2

✓Hardy Weinberg law:-

 a fundamental principle of population genetics: population gene frequencies and genotype frequencies remain constant from generation to generation if mating is random and if mutation, selection, immigration, and emigration do not occur.

------------>>>>>>>>>

✓Significance:-

<> This fundamental idea in population genetics was offered by the Englishman G.H. Hardy (a mathematician) and the German W. Weinberg simultaneously in the year 1908. It is known as the Hardy-Weinberg law.

<> The law forms the foundation of population genetics and of modern evolutionary theory. The law states that: both gene (allelic) frequencies and genotype frequencies will remain constant from generation to generation in an infinitely large interbreeding population in which mating is at random and no selection, migration or mutation occurs.

<> Should a population initially be in disequilibrium, one generation of random mating is sufficient to bring it into genetic equilibrium and thereafter the population will remain in equi­librium (unchanged in gametic and zygotic frequencies) as long as Hardy-Weinberg condition persists.
