Meisos I
Cell division reducing # of chromosomes
Interphase
DNA replicates
Prophase I
Chromosome (tetrad) appear & nuclear membrane breaks down
What is tetrad?
Crossing over structure
Metaphase I
Chromosomes line up in pairs
Anaphase I
Pairs separate
Telaphase I
Cytokinesis
Can interphase happen between Telophase I and Prophase II?
Yes, although short and no DNA replication occurs
Prophase II
Chromosomes not in pairs and don’t cross
Metaphase II
Chromosome lines up in a single file
Anaphase II
Chromatids duplicate copies & become undiplicated separate chromosomes
Telephase II
Nucleus reforms & NDA turns from chromosome into chromatin, then cytokinesis
