Variation in levels of divergence between T . californicus GOT1p1 / GOT1p2 paralogs and regions of predicted gene conversion. Divergence (Dxy) between the GOT1p1 and the GOT1p2 paralogs is calculated over a sliding window with a window size of 60bp and a step size of 12bp. Gene conversion events predicted by the program GENECONV are shown as lines above the divergence plots with dashed lines indicating intra-paralog and solid lines indicating inter-paralog gene conversion events. The dots indicate another related signature of gene conversion, sites that are shared between paralogs within a population (either polymorphic or fixed) but not across populations. Results are shown separately for each of four T. californicus populations (SCN, SD, AB, LJS). The full set of predicted regions of gene conversion are given in Additional file 3: Table S2 with associated statistics from GENECONV.
