Figure 4From: Polyploid evolution and Pleistocene glacial cycles: A case study from the alpine primrose Primula marginata (Primulaceae)PCoA scatterplot of ITS clones. Scatterplot inferred from pairwise distances between cloned ITS sequences using the K2P substitution model: P. marginata hexaploids = green squares; P. marginata dodecaploids = red squares; P. allionii = blue triangles; P. latifolia = yellow circles. Ellipses indicate clades I-IV of Figure 3.Back to article page
