Gametic Meiosis vs. Zygotic Meiosis: What's the Difference?
Edited by Huma Saeed || By Sumera Saeed || Updated on October 30, 2023
Gametic meiosis occurs before gamete formation; zygotic meiosis happens after fertilization.
Key Differences
Gametic meiosis and zygotic meiosis are two different life cycle patterns. In gametic meiosis, meiosis occurs before the formation of gametes, ensuring that the gametes are haploid. In zygotic meiosis, meiosis occurs after fertilization, and the zygote is what undergoes meiosis.

Gametic meiosis results in haploid gametes that fuse during fertilization to form a diploid zygote. This is the typical pattern seen in animals. Zygotic meiosis, on the other hand, results in a multicellular haploid organism that forms from the zygote, which is typical in fungi and some algae.

Gametic meiosis is characterized by a dominant diploid stage, where the organism spends most of its life cycle. Zygotic meiosis is characterized by a dominant haploid stage, where the organism spends most of its life cycle as a haploid multicellular organism.

In gametic meiosis, the diploid organism undergoes meiosis to produce haploid gametes. In contrast, in zygotic meiosis, the diploid zygote undergoes meiosis to produce haploid spores, which then grow into a multicellular haploid organism.
