Detailed results of the genetic admixture for the study regions HE.

<p>Every bar symbolises one individual in the investigated areas (a). Colours indicate Structure population assignments. We also provide results of population assignments with DAPC (b), Structure (c) and NewHybrids (d). Shades of grey indicate assignment to one of the admixed hybrid classes, from light to dark grey: F₁ hybrid, F₂ hybrid, backcross to P₁, and backcross to P₂. Coloured dots show individual assignments to CR haplotypes (e) (green circle = <i>C. f. albicus</i> a₁, blue square = <i>C. f. galliae</i> g, red triangle = <i>C. f. sp. r₁</i>, yellow diamond = <i>C. f. fiber</i> f). For visual purposes samples found close to one another were slightly displaced.
