TABLE 1.

The proportion of the predicted contribution of the microbiome (at the finest taxonomic scale using amplicon sequence variants) to gut microbiome transmission between males and females^a

^aRank is based on the mean proportion of the predicted contribution of the microbiome to the gut microbiome transmission between the paired sex partners after pairing. GM, gut microbiome; GMT, putative gut microbiome transmission; W-test, paired Wilcoxon test; P1M, the male in pair 1; P1F, the female in pair 1. Taxa in bold indicate a significant difference in female-to-male and male-to-female microbiome transmission. Red cells indicate a high proportion of contribution to GMT, and green cells indicate a low contribution to GMT. Each number corresponding to the presence of female-source GM in the male GM part represents the mean proportion of the contribution by the specific microbiome in the total female-source gut microbiome present in the male gut microbiome. Each number corresponding to the presence of male-source GM in the female GM part represents the mean proportion of the contribution by the specific microbiome in the total male-source gut microbiome present in the female gut microbiome.
