Prophase I
Metaphase I
• The Chromosome centromeres attach to
spindles
• Homologous chromosomes line up randomly at
the equator
Anaphase I
Telophase I
• Spindle fibers break down, nucleolus
appear
• Chromosomes uncoil to form two
nuclei
• Nuclear membrane appears
surrounding the new sets of
chromosomes
Cytokinesis I
Prophase II
• Chromosomes condense
• Spindles form in each new cell
• Spindle fibers attach to
chromosomes
Metaphase II
• Chromosomes line up randomly at the equator of each
cell
Anaphase II
• Centromeres split
• Sister chromatids separate and move to opposite
poles
Telophase II
• Four nuclei form around chromosomes
• Spindles break down
Cytokinesis II
