Human gametes
A gamete is a haploid cell that fuses with another haploid cell during fertilization in organisms that reproduce sexually. Gametes are an organism's reproductive cells, also referred to as sex cells.

These are haploid cells wherein each of it carries one copy of chromosome. Male gametes are known as sperms while female gametes are known as ova or eggs. The reproductive cells are an outcome of the process of meiosis.
