<p>Samples are divided into two clusters based on their contig expression pattern, discriminating male (blue) and female gonads (red). (M/F)E: male/female at early stage; (M/F)I: male/female at intermediate stage; (M/F)M: male/female at mature stage; (M/F)R: male/female at regression stage; purple or Inv: gonads in sexual inversion; grey or Und: gonad sex is undetermined.
