Fig. 3From: Equus roundworms (Parascaris univalens) are undergoing rapid divergence while genes involved in metabolic as well as anthelminic resistance are under positive selectionChronogram of the P. univalens based on Bayesian coalescent analysis of SNP data using SNAPP. Nodes with high support (posterior probability = 1.00) are filled in red color. Error bars represent the 95% highest posterior densities (HPD). The colored circles represent different populationsBack to article page
