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 (G1) 6 unreplicated 3 pairs of homologues Diploid 3-7 Interphase (S, G2) (replication of DNA) 6 replicated 3 pairs of homologues Diploid 8-11 Early Prophase I (homologous pairing, crossing

• ver)

6 replicated 3 pairs of homologues Diploid 12-22 Late Prophase I (spindle fibers growing and attaching) 6 replicated 3 pairs of homologues Diploid 24-25

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

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

Telophase II (new cells forming) * * 31 Final Gametes 3 unreplicated (per cell) No pairs Haploid 32-34 * 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.
