Phylogenetic Evidence for the Gain and Loss of a Sexually Selected Trait in Sailfin Mollies
Figure 2
Maximum likelihood ancestral state reconstructions (MULTISTATE; [32, 33]) of the presence of the “sailfin” in 12 species of mollies using inferred branch lengths from the shortest length MP and single best ML trees from Ptacek and Breden [15]. Numbers in circles for each node are values based on likelihood ratio tests of significance of “sailfin present” as the ancestral state.
