There are two types of cell division. Mitosis produces two identical diploid daughter cells. Meiosis produces four non-identical haploid gametes (sex cells).
Sexual reproduction uses the process of meiosisReduction division in a cell in which the chromosome number is halved from diploid to haploid., which creates gameteSex cell (sperm in males and ova/eggs in females).. These are sperm and eggs (ova) in animals, and pollen and ova in plants.
The process of meiosis happens in the male and female reproductive organs. As a cell divides to form gametes:
copies of the genetic information are made
the cell divides twice to form four gametes, each with a single set of chromosomes
gametes are haploidA sex cell (gamete) that contains one set of chromosomes.
all gametes are genetically different from each other
During fertilisation, two haploid gametes fuse to form one diploidA cell that contains two sets of chromosomes. cell. This will divide by mitosisA type of cell division which produces daughter cells identical to the parent. to form an organism.
Meiosis occurs in the testes of men and ovaries of women.
Meiosis and mitosis differ because:
mitosis is a form of cell division which produces two identical, diploid body cells
meiosis is a form of cell division which produces four non-identical, haploid sex cells or gametes (sperm and ova in humans)
