Detailed explanation-1: -Asexual mode of reproduction leads to more variation in the offspring as compared to sexual mode of reproduction. Q. Offsprings formed during sexual reproduction exhibits more variation than those formed by asexual method, because, Q.

Detailed explanation-2: -Summary. 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-3: -Genetic variation is increased by meiosis Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. This produces a unique combination of genes in the resulting zygote.

Detailed explanation-4: -Final answer: Recombination is the most common mechanism of genetic variation in the population of sexually reproducing organisms.

Detailed explanation-5: -Assertion: Sexual mode of reproduction produces variation. Reason: Gametes are produced only by mitotic division which involves crossing over between homologous pairs of chromosomes.
