Supporting Table 3. Meiosis in Three Acts-Alignment of meiotic phases with chromosome number, ploidy and slide number in the presentation for the lesson. Diagram Phase Chromosomes Ploidy Slide # Interphase (G 1 ) 6 unreplicated Diploid 3-7 3 pairs of homologues Interphase (S, G 2 ) 6 replicated Diploid 8-11 (replication of 3 pairs of DNA) homologues Early Prophase I 6 replicated Diploid 12-22 (homologous 3 pairs of pairing, crossing homologues over) Late Prophase I 6 replicated Diploid 24-25 (spindle fibers 3 pairs of growing and homologues attaching)

Metaphase I 6 replicated Diploid 26 3 pairs of homologues Anaphase I 6 replicated Diploid* 27 (homologues 3 pairs separating* separating) Telophase I Transitioning from 6 Transitioning 27 (two cells forming) to 3 per cell* from Diploid to Haploid* Early Prophase II 3 replicated (per Haploid 28-30 (two cells have cell) formed, centrioles No pairs have replicated)

Late Prophase II 3 replicated (per Haploid 31 (spindle fibers cell) growing and attaching) Metaphase II 3 replicated (per Haploid 31 (chromosomes cell) lined up in center) No pairs Anaphase II (sister Transitioning from * 31 chromatids replicated to separating) unreplicated*

Telophase II (new * * 31 cells forming) Final Gametes 3 unreplicated (per Haploid 32-34 cell) No pairs * Transient states where chromosomes are separating but cell has not yet divided. We recommend not discussing chromosome number or ploidy during these phases, to avoid confusing students.
