Detailed explanation-1: -Meiosis also differs from mitosis in that it involves a process known as recombination, during which chromosomes exchange segments with one another. As a result, the gametes produced during meiosis are genetically unique.

Detailed explanation-2: -For example, sexual reproduction allows for variation, but gestation usually takes a long time and it requires heavy parental input. Asexual reproduction occurs quickly, but because all of the offspring have the same genetic information, individuals are more susceptible to disease.

Detailed explanation-3: -Sexual mode of reproduction involves contribution of a set of chromosomes from both the parents and hence more variation is produced.

Detailed explanation-4: -Scientists who study how organisms reproduce know that asexual reproduction is more efficient-for one thing, it’s about twice as fast as sexual reproduction, since every offspring can produce more.
