Question

Short note on Hardy weinberg principle?

Answer 1

The Hardy–Weinberg law was developed independently by an English mathematician, G.H. Hardy, and a German doctor, Wilhelm Weinberg.

The law is a foundation of population genetics. It states that the proportions of alleles of all genes in any population will remain the same unless disturbed. That applies to all loci on all chromosomes in the population. 

Possible perturbations are:

♦ gene mutation
♦ natural selection
♦ small population size where random effects like genetic drift and inbreeding may occur. (H/W populations are assumed to be infinite in size.)
♦ migration into or out of the population under study.

Answer 2

According to the Hardy-Weinberg principle, both allele and genotype frequencies in a population remain both stable and generation-that is, they are in a position of equilibrium-unless they are interrupted No specific effects come in contact with them. Outside the laboratory, one or more of these "interference effects" are always effective. Hardy Weinberg equivalent is impossible in nature. Genetic equilibrium is the ideal condition, which provides a baseline on which genetic changes can be measured.

The frequency of alleles in a population remains constant for generations, if the following conditions are followed: random mating, no mutation (alleles do not change), no migration or emigration Being (there is no exchange of alleles between populations), a large size of population and any selection of support or opposition of any symptoms Not Tmk pressure.
In the simplest case of a single gene location with two alleles: Effective allele is denoted by A and ineffective allele A by A and its frequencies are represented by p and q; Freq (a) = p; Freq (a) = q; P + q = 1. If population is in equilibrium, then for freq (aa) = p 2, aa cycles for aA homozygotes in the population, for freq (aa) = q 2, and heterozygotes. Freq (aa) = 2pq will be received.
