Fig. 8From: Genetic structure of Spirometra mansoni (Cestoda: Diphyllobothriidae) populations in China revealed by a Target SSR-seq methodMaximum likelihood tree among 16 geographical populations (See Fig. 1 for abbreviations) constructed with TreeMix. Arrows indicate migration events and are colored according to their migration weight. Horizontal branch lengths are proportional to the amount of genetic drift estimated among populations. The scale bar indicates tenfold the average standard error (s.e.) of the values in the covariance matrixBack to article page
