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.

Meiotic cell division results in the production of 4 daughter cells which are all genetically different to each other.

During meiotic cell division 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.
