a Relative abundances of Firmicutes, Bacteroidetes, Actinobacteria, and Verrucomicrobia phyla estimated by MetaGen. b Relative abundances of the 25 species mapped to one of the four aforementioned phyla. Clusters 1 to 12 are species in Firmicutes, clusters 13 to 22 are species in Bacteroidetes, clusters 23 to 24 are species in Actinobacteria, and cluster 25 is a species in Verrucomicrobia. c Heat map of the correlation of the relative abundance for the 18 individuals (samples). The samples are clustered by hierarchical clustering using complete linkage functions. In all the plots, a subject’s ID can be parsed into three parts: the family ID (1–6), twin or mother (T, M), and body mass index (lean, overweight, or obese)
