Fig. 4From: Chinese woodchucks with different susceptibility to WHV infection differ in their genetic background exemplified by cytochrome B and MHC-DRB moleculesThe neighbor-joining phylogenetic tree of the Chinese woodchuck species. The published cytochrome B sequences of the Chinese woodchuck species (M. himalayana, M. sibirica, M. caudata, M. baibacina, and M. bobak) were downloaded at least two sequences for one species. The 8 cytochrome B alleles were obtained in 37 animals from TR, TD, GD, and WL areas, Qinghai province, China. The neighbor-joining phylogenetic tree was conducted using MEGA5 softwareBack to article page
