NEET BIOLOGY

Detailed explanation-1: -Sexual reproduction requires two parents. Each parent contributes a gamete-a sex cell that has half of the normal DNA of a regular body cell. In males, the gametes are sperm and in females, the gametes are eggs.

Detailed explanation-2: -Two major types of sexual reproduction are syngamy and conjugation. Syngamy refers to the fusion of haploid sex cells resulting in the formation of a diploid zygote. Thus, in essence, syngamy refers to fertilization. It is the most common type of reproduction in multicellular sexual populations, including humans.

Detailed explanation-3: -Asexual reproduction involves one parent and produces offspring that are genetically identical to each other and to the parent. Sexual reproduction involves two parents and produces offspring that are genetically unique.

Detailed explanation-4: -During sexual reproduction, two haploid gametes combine into one diploid cell known as a zygote in a process called fertilization.
