Fig. 4: Mismatch distribution based on the number of pairwise differences in each distribution type in Raphidonema groups.
From: Evolution of snow algae, from cosmopolitans to endemics, revealed by DNA analysis of ancient ice
The lines represent the observed number of pairwise differences in each distribution type (cosmopolitan, multi-region, endemic) within the Raphidonema Groups A (a), B (b) and C (c). Calculations were performed for all distribution types of Raphidonema Groups A and C, for which various cosmopolitan phylotypes were detected. On the other hand, calculations for only multi-region and endemic phylotypes were performed for Raphidonema group B, because no variation was found in cosmopolitan phylotypes.
