Variation in gene frequencies within populations can occur by chance rather than by natural selection. This is referred to as

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.

In Hardy­Weinberg equation, the frequency of heterozygous individual is represented by

According to the Neo-Darwinian theory, which of the following is responsible for the origin of new species

State and explain any three factors affecting allele frequency in populations.

Gene pool is referred to
