Gametes are reproductive cells involved in sexual reproduction. In males, the gametes are sperm cells, which are small and motile, while in females, they are egg cells (ova), which are larger and contain nutrients for early development.

Gametes are haploid, meaning they carry half the genetic material of a normal cell. They are produced through meiosis, a special type of cell division that creates genetic diversity. During fertilization, a sperm and an egg fuse to form a zygote, restoring the full chromosome number and beginning the development of a new organism.

Gametes are essential for genetic variation, reproduction, and the continuation of species. They ensure that offspring inherit traits from both parents, increasing adaptability in changing environments. Without gametes, sexual reproduction would not be possible, and species would rely solely on asexual reproduction. The production and function of gametes vary across different organisms but remain crucial for biodiversity
