Levels of divergence between GOT1Sd / GOT1Sr paralogs from T . californicus with regions of predicted gene conversion. Divergence (Dxy) is calculated across all four populations between the two paralogs of GOT1S with a sliding window of size 50 bp and 10 bp steps. Patterns of divergence were very similar across populations with the slight exception of the SCN population comparison that showed a small peak (0.15) of divergence centered over the 985–1044 window. Only inter-paralog conversion events are given for these two paralogs with population identity shown on the righthand side of the figure. Exonic regions are indicated at the top of the figure. Note that the central intron varies in size between GOT1Sd and GOT1Sr and cannot be aligned. The full set of predicted regions of gene conversion are given in Additional file 3: Table S2 with associated statistics from GENECONV.
