Fig. 2. Venn diagram analysis of genes with germline-enriched expression. Comparisons between major sets of genes define restricted subsets of germline-enriched expression. Numbers of genes within each subset are listed. (A) Combination of the spermatogenesis and oogenesis sets with the hermaphrodite germline-enriched set defines a subset of germline-intrinsic transcripts. (B) Combination of the male and hermaphrodite germline-enriched sets with the spermatogenesis set defines a subset of male germline-specific transcripts.
