Study Notes
Meiosis
- Meiosis is a type of cell division occurring in reproductive organs (testes and ovaries in humans).
- It produces gametes (sperm and egg cells).
- It's a reduction division; it reduces the number of chromosomes from diploid to haploid.
- A diploid cell divides twice to produce 4 haploid cells, which are genetically different.
- The purpose of meiosis is sexual reproduction.
- It's crucial in passing genetic information from parent to offspring, while also creating genetic diversity in future generations.
