Topologies derived from Dat-SRY analyses. A) ML topology obtained with heuristic search, 100 random addition sequence and K80 model. Numbers near nodes correspond to bootstrapping frequencies ≥ 60 estimated with 1,000 replicates. Arrows indicate SRY mutations (base pair position and nucleotide substitutions). B) 50% majority rule consensus topology of 18,000 sampled trees. Numbers at nodes indicate Bayesian proportions.
