Figure 4.

Characterization of LGC17.1 (grey). (a) PCA based on markers located in the collinear (a1) and putatively inverted region (a2). Three main groups were observed in the inverted region consistent with two homokaryotypes (black and green) and heterokaryotypes (red). (b) Observed heterozygosity across the genetic map for each of these groups (b1–b3). (c) Distribution of the three groups across the transect (distance from the Crab end is shown). (d) Boxplot of nucleotide diversity (pi) for the inverted and collinear regions of the groups 1 and 3. Divergence (d_XY) between groups 1 and 3 within (Inv) and outside (Col) the inverted region (e1), as well as across the genetic map (e2)
