MITOSIS

MEIOSIS

The purpose of mitosis is growth, tissue repair, and asexual reproduction. It produces identical cells

The purpose of meiosis is the production of gametes (sperm and egg cells) for sexual reproduction. It creates genetically diverse cells

There is only one division, resulting in two daughter cells

There are two divisions, resulting in four daughter cells

The chromosome number in daughter cells is the same as the parent cell (diploid)

The chromosome number in daughter cells is reduced by half compared to the parent cell (haploid)

Genetic variation is minimal as the daughter cells are genetically identical to the parent cell

Genetic variation is significant due to processes like crossing over, where genetic material is exchanged between chromosomes

Mitosis occurs in most cells of the body for growth and repair

Meiosis occurs only in specialized cells called germ cells, which produce gametes

Daughter cells are genetically identical to each other and the parent cell

Daughter cells are genetically different from each other and the parent cell

The resulting cells are diploid (two sets of chromosomes)

The resulting cells are haploid (one set of chromosomes)

Mitosis can be involved in asexual reproduction, where offspring are genetically identical to the parent

Meiosis is involved in sexual reproduction, where offspring inherit traits from both parents
