Question

how is variation created in population​

Answer 1

Explanation:

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).

Answer 2

Answer:

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).Some of the variations may be helpful to the organisms in the prevailing natural conditions. Organisms with such positive variations would survive. Over the period variations keep appearing in a species. The favorable variations are chosen by natural selection and promotes survival of the species
