Mitosis and meiosis compared It's really important that you don't get meiosis and mitosis confused! Take some time to look at the table below and make sure you understand all the differences between the two types of cell division. Mitosis Meiosis Purpose To make daughter cells identical to the parent cells - eg during growth and repair To produce sex cells ( gametes ) Takes place . . In all cells apart from gametes In the reproductive organs (ovaries and testes) Produces how many cells? Two daughter cells Four gametes What happens to number of chromosomes? Same number as in parent cell Half as many as in parent cell (The original number of chromosomes is restored when two gametes fuse to form a zygote .) How do parent and daughter cells differ genetically? Not at all - genetic material is copied exactly (replicated) Contain a mixture of chromosomes from two parent gametes - so cannot be identical Variation between daughter cells? No - they are clones of each
