Gametic meiosis-zygotic meiosis and sporic meiosis
Explain gametic meiosis, zygotic meiosis, and sporic meiosis?
Expert
Zygotic meiosis refers to the one which happens within the haplontic haplobiontic life cycle. Gametes from the adult haploid individuals join forming the diploid zygote. The zygote undergoes meiosis and produces four haploid cells that through the mitosis develop into the adult individuals. Therefore, in zygotic meiosis the cell that undergoes meiosis is called as the zygote and the gametes are produced through the mitosis. Gametic meiosis refers to that where the meiosis forms the gametes, that is, haploid cells that each of which may join with other gamete resulting the zygote. It takes place in the diplontic haplobiontic life cycle (like, in the humans) where the individual is diploid and meiosis forms the gametes. Sporic meiosis occurs in the metagenesis (alternation of the generations, or diplobiontic life cycle). In this life cycle, cells from diploid individual (known as sporophyte) go through the meiosis generating the haploid spores which do not join with others however instead develop through the mitosis in the haploid individuals (known as gametophytes). In this life cycle, the gametes are formed through the mitosis from cells of gametophyte.
