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: -Sexual reproduction is combining genetic material from two parents, usually from two gametes. How the two cells combine may take many forms, but does not necessarily involve physical contact. Sexual reproduction produces offspring that are genetically distinct from other offspring and from their parents.

Detailed explanation-3: -There are two types of reproduction: asexual and sexual reproduction. Though asexual reproduction is faster and more energy efficient, sexual reproduction better promotes genetic diversity through new combinations of alleles during meiosis and fertilization.

Detailed explanation-4: -Gametes are produced by a type of cell division called meiosis. The process in which two gametes unite is called fertilization. The fertilized cell that results is referred to as a zygote.
