What is the Hardy-Weinberg equilibrium?

Hardy-Weinberg equilibrium refers to the analysis in genetic structure and demographic variations.

Explanation:

The Hardy-Weinberg concept was postulated by Godfrey Hardy and Wilhelm Weinberg in the early twentieth century.  They created a method for determining genotypes and allel frequencies in a non-evolving population. In the case of a gene with two potential alleles, let's name them p and q which represent the allelic frequency. Because we are concerned with frequencies and percentages, the formula equates to 1. And the formula is:

answer increasing the intensity, duration,and frequency of exercise progressively;

during expiration the diaphragm relaxes, which causes the diaphragm to move downwards. the contraction of diaphragm increases the space for expansion of lungs. hence, the diaphragm relaxes and positioned downward during expiration.
