Yearling weight genotype-by-environment interactions. Manhattan plots with -log₁₀ P- values for U.S. Desert Ecoregion (a), U.S. Southeast Ecoregion (b), U.S. High Plains Ecoregion (c), U.S. Arid Prairie Ecoregion (d), U.S. Foothills Ecoregion (e), U.S. Forested Mountains Ecoregion (f), U.S. Fescue Belt Ecoregion (g), and U.S. Upper Midwest and Northeast Ecoregion (h). Lead and supporting SNPs for interactions represented at or above the blue line (P ≤ 1e-05; −log₁₀ P-values ≥ 5.00) for n = 12,388 U.S. Red Angus beef cattle. A summary of all markers passing the nominal significance threshold is presented in Table 7
