Question

Write short notes on Hardy - Weinberg equilibrium.

Answer 1

this principle based on population genetics, frequency of alleles does not change a given population

$pp + 2pq + qq = 1$

every trait have a specific gene for their dominance or recessive expression ,a gene have two alternative form for their expression. alternative form of a single is called allele ,hardy Weinberg equilibrium shows change in allelic frequency is constant, means 1

conditions to fulfill this equilibrium -

1- large population size

2- random mating

3 - No mutation

4- reproductive health is being normal
