Comparing Mitosis and Meiosis

Mitosis - Meiosis

• Occurs during the growth of somatic cells and asexual reproduction  -  occurs during gamete production

• Two daughter cells (offspring) are formed  - four daughter cells (offspring) are formed

• Chromosome number of parent and daughter cell is the same  -  Chromosome number of daughter cells is half the number in the parent cell

• The chromosomes and their genes in each daughter cell is identical  - The chromosomes and their genes in the four daughter cells are not identical

• No crossing over occurs  -  Crossing over occurs

• Offspring produced by mitosis are exact replicates or clones of the parent organism  -  Offspring produced by meiosis in sexual reproduction will show variations among themselves and their parents.
