What is the Difference Between Gametic Sporic and Zygotic Meiosis?
🆚 Go to Comparative Table 🆚The distinction between Gametic, Zygotic, and Sporic meiosis depends on the stage of the life cycle when meiosis occurs:
- Gametic Meiosis: This type of meiosis occurs during the formation of gametes, which are the male and female sexual cells of organisms. Gametes are haploid cells containing only one set of chromosomes. In the gametic life cycle, the gametes (egg and sperm) are the only haploid cells produced.
- Zygotic Meiosis: In the zygotic life cycle, meiosis occurs immediately after the fusion of gametes to form the zygote. This life cycle is the simplest sexual life cycle and is common among fungi and protists. The zygote undergoes meiosis to produce haploid cells.
- Sporic Meiosis: This type of meiosis occurs during sporogenesis, which is the production of spores. In the sporic life cycle, there is an alternation between multicellular haploid and diploid organisms. The diploid zygote first replicates by a series of mitotic divisions to form a multicellular diploid known as a sporophyte. The sporophyte undergoes meiosis and produces haploid spores.
In summary, Gametic meiosis takes place during the formation of gametes, Zygotic meiosis occurs in the zygote, and Sporic meiosis occurs during the production of spores.

Here is a table comparing gametic meiosis and zygotic meiosis:
Aspect | Gametic Meiosis | Zygotic Meiosis |
---|---|---|
Occurrence | During gamete formation | After gametes fuse into a zygote |
Life Cycle Stages | Completed in the diploid phase of the life cycle | Completed in multicellular, haploid stage of the life cycle |
Gametes | Produces haploid male and female gametes | Produces haploid spores from the zygote |
