Formed when homologous chromosomes cross-over
tetrad
Chromosomes line up in the center of the cell
Metaphase II
Two non-identical cells are formed
Cytokinesis I
Four non-identical haploid cells are formed
Cytokinesis II
holds sister chromatids of a chromosome together
centromere
Tetrads line up in the middle of the cell
Metaphase I
Sister chromatids of chromosomes separate and move apart
Anaphase II
Cytoplasm starts to divide and form two nuclei
Telophase I
New nuclei are formed around the chromosomes of each daughter cell
Telophase II
Homologous move to opposite sides of the cell
Anaphase I
contains half of the chromosome number of parent cells
haploid
The nuclear membrane reforms and chromosomes do NOT replicate anymore
Prophase II
Homologous chromosomes pair up and cross-over
Prophase I
