Average, SD, and range of bivalents, chiasmata, and ring bivalents per cell in Arabidopsis asy1, shoc1, mus81 single mutants and asy1/shoc1 and asy1/mus81 double mutants. Note: the bivalent frequency between asy1 and asy1/mus81 was not significantly different, while the number of ring bivalents in asy1/mus81 was reduced, causing the observed reduction in chiasma frequency. n=number of cells.
