Detailed explanation-1: -So the right answer for this question is to the right answer is a sexual reproduction does not lead to genetic variation.
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: -Sexual reproduction has the potential to produce tremendous genetic variation in offspring. This variation is due to independent assortment and crossing-over during meiosis, and random union of gametes during fertilization.
Detailed explanation-4: -Offsprings are identical to the parent genetically and morphologically. They are the exact copy or clone of the parent. There is no recombination of genetic material takes place in asexual reproduction. Hence, there is no variation or genetic variability seen in the individual produced by asexual reproduction.
