Initiating force of evolution is

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

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?

Primary source of allelic variation is

In a population of $1000$ individuals $360$ belong to genotype $AA, 480$ to Aa and the remaining $160$ to $aa$. Based on this data, the frequency of allele $A$ in the population is

According to the Darwin's theory of evolution, differences between the species occurs due to
