Spermatophore proteins are encoded by both testes- and MAGs-biased genes.
(a) Male reproductive tract. Scale bar = 1.5 mm. A closer view of the testes and their respective deferent ducts are shown in the box. (b) Relative protein abundance in the spermatophore (emPAI) as compared to the ratio of MAG/Testes normalized expression (FPKM). Both axes are labeled with logarithmic values.
