Which is the most common mechanism of genetic variation in the population of a sexually reproducing organism ?
Genetic drift
Recombination
Transduction
Chromosomal aberrations
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
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.

Type $I$ Type $II$ Type $III$
Hardy-Weinberg equilibrium is not affected by which of the following factors?
