NEET BIOLOGY

Detailed explanation-1: -Sexual reproduction provides genetic diversity because the sperm and egg that are produced contain different combinations of genes than the parent organisms. Asexual reproduction, on the other hand, does not need sperm and eggs since one organism splits into two organisms that have the same combination of genes.

Detailed explanation-2: -The process of sexual reproduction introduces variation into the species because the alleles that the mother and the father carry are mixed together in the offspring.

Detailed explanation-3: -Explanation: The sperm and egg that is produced during sexual reproduction contain different gene combinations as compared to the parent organisms. Asexual reproduction doesn’t require eggs and sperms production as the splitting of one organism into two occurs thus contains the same combination of genes.

Detailed explanation-4: -Sexual reproduction increases variation among offspring because the sperm and egg have different combinations of genes than their parent organisms. Asexual reproduction does not have variation from sperm and egg because the offspring is an exact copy of a single parent.

Detailed explanation-5: -Despite the two-fold cost of sex, most of the higher animals reproduce sexually. The advantage of sex has been suggested to be its ability, through recombination, to generate greater genetic diversity than asexuality, thus enhancing adaptation in a changing environment.
