Study Notes
Types of Meiosis
- Three main life cycle types: zygotic, gametic, and sporic meiosis.
Zygote
- Defined as the product formed from the fertilization of two gametes.
Spores
- Haploid cells produced by meiosis in sporophyte (2n) individuals; they can develop without fertilization.
Meiosis
- A process that reduces diploid (2n) cells to haploid (1n) cells.
Mitosis
- Process that results in the duplication of diploid (2n) cells into identical diploid cells.
Zygotic Meiosis
- Zygote immediately divides by meiosis, producing four haploid cells.
- The haploid cells then undergo mitosis, leading to haploid individuals; gametes are formed through differentiation.
- No diploid stage exists in this cycle.
Gametic Meiosis
- Involves the formation of haploid gametes via meiosis in diploid individuals.
- The fusion of gametes generates a diploid zygote.
- The zygote subsequently undergoes mitosis to create a new diploid individual.
Sporic Meiosis
- Begins with the production of haploid spores from the sporophyte (2n).
- Spores undergo mitosis to generate gametophytes (1n).
- Gametes produced from gametophytes fuse to create a diploid zygote, which then undergoes mitosis to form a new sporophyte (2n).
