The heritability and significant variants of the rumen microbiota of dairy cows. A The proportion of highly heritable microbes at the species level at the domain level, the proportion of highly heritable KEGG pathways at level 3 at level 1, and the proportion of highly heritable CAZy modules at the family level at the class level were calculated. B The linear relationship between node attributes (degree, closeness, and betweenness) and heritability. P < 0.05 was considered to indicate a linear relationship. C Manhattan plot of highly heritable rumen fat subsets from the top 100 microbes at the species level. The significance threshold was 1/nSNP = 4.28E-07. The extremely significant threshold was 0.05/nSNP = 2.14E-08
