Key Stage 4
Meaning
Meiosis is the process of asexual reproduction where a parent cell produces four haploid daughter cells known as gametes that are all genetically unique.
Noun: Meiosis
Adjective: Meiotic
About Meiosis
- Meiosis is how multicellular organisms (including humans) produce gametes for sexual reproduction.
- The 4 daughter cells are all genetically different to one another.
- During meiosis the nucleus divides into two separate diploid nuclei before dividing a second time to produce 4 haploid nuclei.
- The four daughter cells are called haploid cells because they contain half the number chromosomes needed to grow a new organism.
