What occurs in meiosis but NOT mitosis

• crossovers between homologous chromosomes

• crossovers between sister chromatids

• spindle formation

• chromosome number is conserved

What process occurs in BOTH mitosis and meiosis

• crossovers in prophase I

• separation of sister chromatids

• anaphase II

• division of two genetically identical nuclei

What does mitosis do?

• regulates the cell cycle

• promotes spindle formation

• suppresses cancer

• results in the division of two genetically identical nuclei
