Fig. 4From: Deeply divergent sympatric mitochondrial lineages of the earthworm Lumbricus rubellus are not reproductively isolatedNeighbor-Joining tree generated from the between-individual distance matrix (uncorrected p-distance) based on all 5712 SNPs from the RADseq data. Each dot represents an individual Lumbricus rubellus earthworm, and the color represents the population of origin. Bootstrap support values indicate grouping of individuals according to the population of originBack to article page
