Interphase Chromosomes Duplicate Prepares to Divide

Prophase I Homologous Chromosomes pair up to form a
Tetrad Crossing-over Occurs

Metaphase I Homologous Chromosomes line up
across the center of the cell

Anaphase I Spindle fibers pull each Homologous
Chromosome pair toward opposite ends of the cell

Telophase I and Cytokinesis Telophase – Nuclear membrane reforms
around each cluster of chromosomes
Cytokinesis – Follows Telophase, forming two new cells

Prophase II Chromosomes (with 2 Chromatids)
become Visible

Metaphase II Chromosomes line up at the center of
the cell

Anaphase II Paired (Sister) Chromatids separate

Telophase II and Cytokinesis Telophase II – Nuclear membrane reforms Cytokinesis – 4 new genetically different,
haploid cells are produced
