can you please explain hardy- weinberg principle in a simplified way.

The Hardy-Weinberg Law states (using a formula p2 + 2pq+q2) an equilibrium of allele frequencies in a gene pool  remains in effect in each succeeding generation of a sexually reproducing population if five conditions are met. They are random mating and the absence of mutation, gene flow, genetic drift and selection. But allele frequencies may change from one generation to the next, resulting in evolution. The Hardy-Weinberg law explains the factors that cause evolution. Hardy-Weinberg equilibrium states the constancy of gene pool frequencies that remains across generations.


This topic is well explained in our study material so please follow the given link.!!/QxTx4a5fRRCWToHTBsIlSQ!!
