Table 2 The standardized-lineage-specific transitions (S-LSTs) in sex-biased status (transitions between testis-biased, ovary-biased or unbiased status) in the gonads from a conserved ancestral state. The six possible categories of transitions in sex-biased expression are shown per species. Comparison of the ratio of S-LSTs are shown. *Indicates a Chi² test between the two transition types per contrast (using counts of transitions and ancestral states) was statistically significant (*P < 0.05 and ≥ 0.0001, **P < 0.0001). Raw counts of transitions are in Additional file 1: Table S4
