Figure 6.

Map showing the geographic distribution of the variants of 3 SNPs. Nucleotide variants are shown for position 119 of intron LANCL1-4, position 282 of intron PRPF31-3 and position 39 of intron DHRS3-3. For each specimen, the alleles of both chromosomes are represented with two adjacent points. The derived mutation (as deduced from the Desmana outgroup) is shown in red. Some points have been latitudinally shifted to reveal specimens of the same location. The purple line indicates the genetic barrier identified by the Monmonier’s Maximum Difference algorithm (only the intersection with the species distribution area is shown).
