Gametogenesis is the process of the formation of haploid gamete from diploid gonads. Gametes are formed by specialized meiosis/reductional division. Although both sperm and OVA are very dissimilar morphologically yet both comprise similar phases of sequentially changes. Gametogenesis is two types first one is spermatogenesis and the second one is oogenesis. Spermatogenesis is the process of formation of functional sperm/ spermatozoa from diploid spermatogonia. Oogenesis is the formation of haploid ova/ video from the diploid egg mother cell/ oogonia of the ovary. So take the Gametogenesis quiz and no more about gametogenesis.
