Question

Enlist various factors that are responsible for changing gene frequency.​

Answer 1

Explanation:

Four major forces are usually listed for changing gene frequencies in populations, namely migration, mutation, selection and random genetic drift. These forces constitute the mechanisms underlying the evolutionary process.

Answer 2

Various factors that are responsible for changing gene frequency are

migration, mutation, selection, and random drift.

• Migration: It is a natural behavior of many species when they move on a large scale to a different environment.

• Mutation: It is a process when permanent changes occur either in genes or chromosomes which resulted in a genetic disorder.

• Selection: When an organism is adapted to its environment and reproduces by the means of genetic changes either through the natural or artificial selection process.
• Random drift: During the evolutionary changes when a  genetic drift or deviation is observed in a random manner from generation to generation.
