NEET BIOLOGY

Detailed explanation-1: -During sexual reproduction the genetic material of two individuals is combined to produce genetically diverse offspring that differ from their parents. The genetic diversity of sexually produced offspring is thought to give species a better chance of surviving in an unpredictable or changing environment.

Detailed explanation-2: -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: -Sexual reproduction meant that an organism could combine half of its genes with half of another’s genes, which creates new combinations for each generation.

Detailed explanation-4: -Sexual reproduction has an advantage over asexual reproduction in a changing or unstable environment. Changes in the environment often support directional selection; this is highly favored by sexual reproduction and the population reaches stability very quickly.

Detailed explanation-5: -Asexual reproduction generates offspring that are genetically identical to a single parent. In sexual reproduction, two parents contribute genetic information to produce unique offspring.
