Explanation:
Detailed explanation-1: -Mutations are the original source of genetic variation. A mutation is a permanent alteration to a DNA sequence.
Detailed explanation-2: -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).
Detailed explanation-3: -This independent assortment, in which the chromosome inherited from either the father or mother can sort into any gamete, produces the potential for tremendous genetic variation.
