Question

The migration of gene into a population from other population by interbreeding is called as

• A. Gene pool
• B. Gene flow
• C. Genetic drift
• D. Gene erosion

Answer 1

The correct option is B Gene flow

A gene pool is defined as the set of all genes of a particular species. Transfer of alleles or genes from one population to another is called as gene flow or gene migration. The migration of individuals in and out of the population is the main cause of gene flow. A change in the frequency of an allele in a population due to random sampling of organisms is called as genetic drift or allelic drift. Gene erosion is defined as loss of genetic diversity of an already endangered species. Option B is the correct answer.
