Fig. 3. Extent of genetic divergence between Tetranychus species and among Tetranychus urticae lines.

Fig. 3

Genetic differentiation between 26 iso-female Tetranychus urticae (green) lines (this study), 30 additional T. urticae lines (28 green and 2 red lines, denoted as ‘other’ and green or red as indicated) and two other Tetranychus species (T. turkestani and T. kanzawai) as assessed by principal component analyses (a, b), as well as by c pairwise genome-wide Fst calculations (the extent of shading reflects Fst levels as indicated, bottom right). For b genetic differentiation assessed by a principal component analysis, but limited to T. urticae green lines (see dashed lines connecting to a), is shown. d Genetic differentiation among the 26 iso-female green lines (this study) as assessed in a sliding window Fst analysis across the T. urticae genome (the three scaffolded chromosomes are as indicated with alternative shading; unplaced and concatenated scaffolds are shaded green, far right).
