Detailed explanation-1: -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-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: -Asexual reproduction is a mode of reproduction in which offsprings arise from a single organism and inherit the genes of that parent only; it does not involve the fusion of gametes. The offspring produced from asexual reproduction is exact copy of the parent. What is a clone?

Detailed explanation-4: -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. Gametes are haploid cells, and each cell carries only one copy of each chromosome.

Detailed explanation-5: -Each resulting cell, or gamete, resulting from meiosis has only half the amount of DNA as the parent cell. So in order to form a new organism, two gametes–the sex cells, sperm and egg–must fuse, further mixing the genes to produce more genetic diversity.
