What is Meiosis?
What is Meiosis?
A type of cell division, occurring in reproductive organs, that produces genetically different haploid gametes from a diploid cell.
Gametes definition
Gametes definition
Reproductive cells (sperm and egg) produced by meiosis.
Meiosis: Chromosome change?
Meiosis: Chromosome change?
Meiosis reduces the number of chromosomes from diploid to haploid, meaning the number of (genetic) copies is halved.

Study Notes
Meiosis
- Meiosis is a cell division process that occurs in reproductive organs (testes and ovaries in humans)
- It produces gametes (sperm and egg cells)
- It is a reduction division, reducing the number of chromosomes from diploid to haploid
- A diploid cell divides twice to create 4 haploid cells, which are genetically different
- The purpose of meiosis is sexual reproduction
- It is fundamental in passing genetic information from parent to offspring, while also creating genetic diversity in future generations.
