Extended Data Table 2 No significant association between ancestral or genetic similarity and the gut microbiome

From: Environment dominates over host genetics in shaping human gut microbiota

  1. Each cell contains the P value of a single or of multiple statistical tests, testing whether individuals who are more similar according to ancestry or genetic kinship (in columns) are also more similar according to (i) microbiome β-diversity (using Bray–Curtis dissimilarity); (ii) microbiome α-diversity (using Shannon diversity); (iii) abundance of specific taxa; or (iv) genetic kinship (in rows). The first column includes n = 582 non-admixed individuals, the second includes 946 individuals and the third includes 715 unrelated genotyped individuals. P values in the first column are based on Kruskal–Wallis tests (using the top 5 microbiome PCOs for Bray–Curtis dissimilarity, and the top 5 genetic principal components for genetic kinship); P values in the other columns are based on Mantel tests (Methods).
