Figure 5. No difference in transition rate from homomorphic sex chromosomes to ESD versus heteromorphic sex chromosomes to ESD in fish.
Posterior distribution of the difference in transition rates between homomorphic sex chromosomes and ESD, and heteromorphic sex chromosomes and ESD. Across the 10 datasets and the entire analyses, 43.7% of the posterior distribution supports a higher rate of transitions from heteromorphic sex chromosomes to ESD, but this is not significant. The posterior distributions of the transition rates between heteromorphic sex chromosomes and ESD and between homomorphic sex chromosomes and ESD are significantly greater than zero (Supplemental Figures 2 and 3).
