Learn a gamete definition and what occurs during gamete formation. Also learn how to differentiate between gametes vs zygotes, plus see gametes examples.
Gametes: Gamete is the term given to the reproductive cells of sexually reproducing organisms. For example, sperm and egg cells in humans are gametes. Gametes are haploid cells, which means they have only half the number of chromosomes of a fully formed organism. Key Terms: Somatic cells - all of the cells in an organism's body excluding the gametes or sex cells. Ploidy level - this term ...
Chromosomes in Gametes: Normal human somatic cells are diploid and contain a total of 23 pairs of chromosomes (total of 46 chromosomes). One of these is a pair of sex chromosomes, and the other 22 pairs are autosomes. Gametes, also called sex cells, have a different number of total chromosomes that do not exist in pairs.

By definition, gametogenesis is the process of the production of gametes (sex cells) from germ cells in an organism, where haploid cells (n) are produced from diploid cells (2n). In animals, cells ...
