NEET BIOLOGY

Detailed explanation-1: -In the human reproductive process, two kinds of sex cells, or gametes (GAH-meetz), are involved. The male gamete, or sperm, and the female gamete, the egg or ovum, meet in the female’s reproductive system. When sperm fertilizes (meets) an egg, this fertilized egg is called a zygote (ZYE-goat).

Detailed explanation-2: -The correct option is C fertilisation. The process of fusion of male and female gametes is called fertilisation. It results in the formation of zygote. The zygote develops to form an embryo.

Detailed explanation-3: -The fusion of the egg and sperm is called fertilization. Fertilization is the process by which the male and female gametes fuse to give rise to zygote.

Detailed explanation-4: -During fertilization, sperm and egg fuse to form a diploid zygote to initiate prenatal development. In mammals, fertilization involves multiple ordered steps, including the acrosome reaction, zona pellucida penetration, sperm–egg attachment, and membrane fusion.
