↵a Epistasis tests were conducted in the respective double mutant backgrounds by analyzing genetic mosaics with losses of the kin-1(+)-rescuing array in the somatic gonad lineage. Genetic mosaics were sought in animals bearing the tnEx109[kin-1(+) sur-5::gfp] extrachromosomal array. The genotype refers to the somatic cells of a gonad arm in the genetic mosaics.
