If mating is random, population is large and mutation does not occur; then gene frequencies of population from generation to generation remain constant. This was put forwarded by

Natural selection where more individuals acquire specific character value other than the mean character value, leads to:

Random genetic drift in a population probably results from

A population is in Hardy- weinberg equilibrium for a gene with only two alleles. If the gene frequency of an allele $A$ is $0.7$, the genotype frequency of $Aa$ is

Which is the most common mechanism of genetic variation in the population of a sexually reproducing organism ?

If gene migration happens multiple times, it would lead to
