Figure 3.

Heritability and 95% confidence intervals of four alpha diversity indices (on top) and 71 genera (below) estimated jointly for data of growing pigs fed a conventional diet and growing pigs fed a high-fiber diet combined.

Legend:

Orange = heritability not significantly different from zero (P > 0.05); blue = heritability significantly different from zero (P < 0.05). The 5% threshold was obtained by bootstrapping genera abundances to individuals and determining heritability for each reassignment, with 5000 replicates.
