Question

why variation acts as a tool for evolution​

Answer 1

Explanation:

Genetic variation is an important force in evolution as it allows natural selection to increase or decrease frequency of alleles already in the population.

Answer 2

Answer:

Genetic variation is a measure of the variation that exists in the genetic makeup of individuals within population.

Genetic variation is an important force in evolution as it allows natural selection to increase or decrease frequency of alleles already in the population.

Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism’s offspring).

Genetic variation is advantageous to a population because it enables some individuals to adapt to the environment while maintaining the survival of the population.
