The Complex Genetic Architecture of the Metabolome

Genome-wide association hotspots.
Plotted are the average numbers of associated metabolites per gene, estimated at sliding windows of 100 genes, for Expt. A (top) and Expt. B (bottom). Indicated on the axes are previously reported linkage hotspots (red lines; [10]), and two previously reported recent positive selective sweeps (pink S; [60]).
