brummer expression in males is necessary for maintaining male fertility.
(A) Males with whole-body loss of brummer have a significantly decreased number of progeny after 2 days, 4 days, and 6 days of mating (p = 2.2 × 10−16, 9.7 × 10−12, and 4.6 × 10−6, respectively; Student t test at each time point). Asterisks indicate a significant difference between two sexes, two genotypes, or two time points (*p < 0.05, **p < 0.01, ***p < 0.001). See S1 Table for list of all multiple comparisons and p-values. Error bars on graphs represent SEM. Quantitative measurements underlying all graphs are available in S4 Data. M, male; ns, no significant difference between two sexes, two genotypes, or time points.
