Detailed explanation-1: -Sexual reproduction occurs when the sperm from the male parent fertilizes an egg from the female parent, producing an offspring that is genetically different from both parents.

Detailed explanation-2: -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-3: -The zygote goes through a process of becoming an embryo and developing into a fetus. The male reproductive system and the female reproductive system both are needed for reproduction. Humans, like other organisms, pass some characteristics of themselves to the next generation.

Detailed explanation-4: -Animals and plants can reproduce using sexual reproduction. In sexual reproduction new organisms are produced from the fusion of a male sex cell with a female sex cell. This fusion of gametes is called fertilisation.

Detailed explanation-5: -Sexual reproduction always involves the formation of male and female gametes produced by two different organisms of the same species.
