Definition of Gametogenesis

Gametogenesis is a process through which the gametes i.e. eggs and sperms are formed in an organism. This process takes place in sexually reproducing organisms. The formation of egg cells and sperm cells is termed as oogenesis and spermatogenesis respectively. This process takes place by the division of diploid gametocytes by meiosis and various haploid gametes are produced.


The gametes in the plants are produced by mitosis during gametophyte phase. The important feature of gametogenesis is meiosis during which the homologous chromosomes are paired up and genetic recombination takes place between them. The recombination allows the diversity within the species.
