1) Homologous chromosomes pair up together and crossing over occurs: 2) Sister chromatids separate and move to opposite ends of the cell:

3) 2 haploid daughter cells form; the sister chromatids are still attached:

4) Duplicated homologous chromosome match up at the middle of the cell:

5) Homologous chromosomes move towards opposite ends of the cell (sister chromatids are still connected by the centromere):

6) Sister chromatids line up in the middle of the cell:

7) 4 unique haploid daughter cells are formed:
