Genome-Wide Association Studies across Environmental and Genetic Contexts Reveal Complex Genetic Architecture of Symbiotic Extended Phenotypes.

However, consistent with an a priori expectation that symbiotic extended phenotypes are governed by many variants with small effects, we indeed found that within a single GWAS, variant effect sizes tended to be small, with few approaching significance after conventional Bonferroni correction and additional analyses (see Fig.
