Bimodal

Definition
AI-generated

Distribution or histogram with two dominant modes—can signal mixture populations or dichotomized liability.

Why it matters in GWAS

Statistical concepts underpin GWAS significance, effect estimation, relatedness random effects, multiple testing, fine-mapping priors, and post-GWAS multivariate methods.

Example usage

"The phenotype histogram was bimodal, suggesting either mixed subpopulations or a thresholded clinical ascertainment process."
