Answer 2

Answer:

Sexual reproduction is the source of variation. Mixing of two organisms give rise to new recombinants or variants. Sexual reproduction involves the mating of germ cells also known as gametes. These gametes are haploid in nature, that is, they have half set of chromosomes. These gametes are formed through the process of meiosis. When male gametes and female gamete each with haploid set of chromosomes combine they will form a diploid zygote. Zygote undergo repeated divisions to form a new organism.

In human male gamete is small and motile whereas female gamete is large and non-motile.
