Fig. 3From: Base-substitution mutation rate across the nuclear genome of Alpheus snapping shrimp and the timing of isolation by the Isthmus of PanamaA Proportion of loci shared among individuals in the Am4s2 dataset. Loci shared between individuals (black circles) or successfully amplified within an individual (red circles) expressed as the proportion from 0 to 1 of all 48,062 loci scored in the Am4s2 dataset. Plotted with the phylogenetic tree based on maximum likelihood inference, with branch lengths scaled in substitutions per nucleotide.
