Lesson outcome
I can explain how a type of cell division called meiosis makes gametes for sexual reproduction.
Show transcript
Reproduction is part of the life cycle of all organisms; sexual reproduction requires specialised cells called gametes.
Gametes are made from body cells by a type of cell division called meiosis.
During interphase the chromosomes are copied; meiosis follows this and includes two rounds of cell division.
The gametes made by meiosis have half the usual number of chromosomes (one from each pair in the original body cell).
Mitosis produces 2 genetically identical diploid cells, whereas meiosis produces 4 genetically different haploid cells.
