C: mean cell chiasma frequencies. n: number of cells. s: short arm. l: long arm. For each genotype, the upper row indicates the mean chiasma frequency per bivalent arm (s and l); the bottom row includes the mean chiasma frequency per bivalent (s + l), and the contribution to the total chiasma frequency (as proportion of total cells) in parentheses. Asterisks indicate significant differences with the corresponding wild type in a Student’s t-test (*p < 0.05; **p < 0.01; ***p < 0.001).
