meg-1 exhibits diverse genetic interactions with glh-1 and pgl-1. (A) DAPI-stained animals showing the most common germline phenotype in wild-type, glh-1, pgl-1, meg-1, glh-1;pgl-1, glh-1;meg-1, pgl-1;meg-1, and glh-1;pgl-1;meg-1 adults. Arrow indicates position of vulva. Bar, 50 μm. (B) pgl-1;meg-1 sterile adults have more germ cells than meg-1 sterile adults. Average number of germ cells was counted in fixed sterile adults stained with DAPI to visualize nuclei. n ≥ 17 sterile animals for each genotype; three independent trials were averaged together and standard error was determined (*P < 0.05, **P < 0.005).
