Detailed explanation-1: -Sexual reproduction results in infinite possibilities of genetic variation. In other words, sexual reproduction results in offspring that are genetically unique. It is this variation that is the essence of evolution. Without genetic differences among individuals, “survival of the fittest” would not be likely.

Detailed explanation-2: -Sexual reproduction, which involved the formation of gametes through meiosis and the fertilization of the gametes where two gametes fuse to make one diploid cell, offers the greatest potential for genetic diversity.

Detailed explanation-3: -Unlike sexual reproduction, asexual reproduction only introduces genetic variation into the population if a random mutation in the organism’s DNA is passed on to the offspring.

Detailed explanation-4: -Advantages of sexual reproduction arise from genetic recombination in cross-fertilisation, which purges deleterious mutation and increases genetic variability in the population [8-10], enhancing adaptation in a changing environment.
