Gametic Meiosis vs. Sporic Meiosis

Meiosis is of three types, depending on the stage where it occurs. The main difference between these two types of meiosis is, that in gametic meiosis the process of meiosis occurs during the formation of gametes and results in haploid gametes formation. In sporadic meiosis, the division occurs during sporogenesis and results in the formation of a haploid number of spores. So, these two types of meiotic divisions depend upon the place and time of the occurrence of the process of meiosis.

Key Differences

Gametic meiosis gives rise to gametes, and sporic gives rise to spores.
Gametic meiosis occurs in gametes and sporic during sporogenesis.
Gametic meiosis have diplontic life style. and sporic meiosis has a diplohaplontic life cycle.

What is Gametic Meiosis?

Gametic meiosis occurs in gametes, during their formation and eventually gives results in the formation of a haploid number of gametes. Then these gametes fuse together in the process of fertilization and give rise to a zygote. It has a diplontic lifestyle. This zygote then undergoes mitosis and is converted into an individual. In sexually reproducing organisms, this type of meiosis takes place during the formation of gametes and then in the transfer of those gametes to the formation of a zygote.

What is Sporic Meiosis?

This type o division occurs during the process of sporogenesis and results in the formation of haploid spores. Spore divides to form gametophytes which eventually form gametes. A diploid sporophyte is formed as a result of the fusion of those gametes. It has a diplohaplontic life cycle and is common in plants. Sporic meiosis also occurs in the life cycle of ferns and mosses.
