Genomic Fit and Environmental Mismatch: The Tradeoff Model of Polygenic Operating Range

Abstract

Why do "harmless" common genetic variants trigger catastrophic failures under specific environmental stress?Moving beyond reductionist "one-variant-one-disease" paradigms, this monograph introduces the Tradeoff Model of Polygenic Operating Range. It reframes common polymorphisms (SNPs) as conditional modifiers of a system's collective buffering capacity within a dynamic environment.The paper introduces the mechanism of environmental amplifiers and leverages recent convergent data linking organophosphorus pesticide exposure, gut microbial depletion, and neuroexcitatory shunting to illustrate multi-node genomic interaction.
