Median joining network derived from reconstructed DNA sequence haplotype of <i>CRTISO</i> gene.

<p>Haplotypes are displayed at network nodes and are symbolised by circles whose diameter is proportional to the frequency in the sample. The code number of the haplotypes is written in the circle centre. Perpendicular hashes on the lines joining haplotypes represent substitutions. When too numerous, they are displayed as slanting hashes with the number of substitutions differentiating two network nodes. The main clusters are identified by dotted boxes. (A) The black and grey proportions of each circle represent respectively the proportion of individuals from the Western and Eastern genetic groups (estimated by STRUCTURE analysis) sharing the same haplotype. (B) Colours represent the proportion of different colour groups: white, yellow, orange, red and purple.
