Write the importance of variation
  • 1 answers

Meghna Thapar 5 years, 2 months ago

  • 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.
