Write short note on Hardy - Weinberg principle.
 

Factor affecting the Hardy-Weinberg principles are

$I.$ gene flow

$II.$ genetic drift

$III.$ mutation

$IV.$ genetic recombination

$V.$ natural selection

The correct combination is

Gene flow occurs through generations. Gene flow can occur across language barriers in humans. If we have a technique of measuring specific allele frequencies in different population of the world, can we not predict human migratory patterns in pre-history and history ? Do you agree or disagree ? Provide explanation to your answer.

According to Hardy-Weinberg principle, allele and genotype frequencies in a population will remain constant from generation to generation in the absence of other evolutionary influences. It makes several assumptions which were given below.

$i.$  Random Mating

$ii.$  Sexual Reproduction

$iii.$  Non-overlapping Generations

$iv.$  Occurrence of Natural Selection

$v.$  Small size of population

Identify two assumptions which do not meet for a population to reach Hardy-Weinberg Equilibrium?
