Fig. 4. Male germline-specific genes. Shown are relative levels of gene expression of several indirect comparisons between genotypes for eight genes with significantly male germline-enriched expression, but no evidence of hermaphrodite-enriched expression. him, him-5 males; glphim, glp-4;him-5 males; N2, wild-type hermaphrodites; glp, glp-4 hermaphrodites; fem-3, fem-3(gf) hermaphrodites; fem-1, fem-1(lf) hermaphrodites. All comparisons shown were made between adult animals, except for column 4. Yellow represents increased expression in the numerator of each comparison, while blue represents increased expression in the denominator of each comparison.
