Interphase: Four original chromosomes with alleles
marked
Interphase: Chromosomes after doubling, alleles marked
Prophase 1: chromosomes cross over with homologue
Prophase 1: genetic recombination
Metaphase 1: line up in pairs with homologue; spindle
present
Anaphase 1: spindle pulls pairs apart
Telophase 1 & Cytokinesis: paper cell splits (cut in two)
Prophase 2: (chromosomes not lined up yet)
Metaphase 2: Chromosomes line up singly
Anaphase 2: chromatids separate to opposite poles
Telophase 2 and Cytokinesis: paper cells split (4 new cells)
