MetAMOS comparative heat map for sexual dimorphism study. Heat map calculated on the species-level diversity in the gut microbiome of six healthy Danish adults (as reported by MetaPhyler; full species listing for this experiment available for download from the MetAMOS website). Only taxa with abundance > 1% in all samples are reported. Sex is indicated on the x-axis, while individual species are labeled on the y-axis. The gradient from dark to light indicates the z-score of the abundance from low to high.
