NEET BIOLOGY

Detailed explanation-1: -During sexual reproduction, two haploid gametes combine into one diploid cell known as a zygote in a process called fertilization. The nuclei from the gametes fuse, and each gamete contributes half of the genetic material of the zygote.

Detailed explanation-2: -Gametes are an organism’s reproductive cells. They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm.

Detailed explanation-3: -Sexual reproduction always involves the formation of male and female gametes produced by two different organisms of the same species.

Detailed explanation-4: -Animals also produce gametes for fusion. But the fusion of gametes may take place inside or outside the body. Based on this, fertilization is of two types – internal and external fertilization.
