Question
______________ refers to the process by which certain species migrate from their original location to a new location, hence changing the allele frequency.
- Gene drift
- Gene migration
- Gene travel
- Genetic recombination
The correct answer is: Gene migration
When migration of a section of population to another place and population occurs, gene frequencies change in the original as well as in the new population. New genes/ alleles are added to the new population and these are lost from the old population. There would be a gene flow if this gene migration, happens multiple times. If the same occurs by chance, it is called genetic drift.
