Gene loss under constant cold reveals “natural knockout” loci in Antarctic notothenioid fishes

2026-06-10

Abstract excerpt

<h4>Background</h4> Gene loss is a major but often underappreciated mode of genome evolution. Genes loss can reflect relaxed selective constraint, neutral decay, compensation, or adaptive change; once fixed, however, they alter the inherited gene complement and can shape the evolutionary trajectories available to descendant lineages. Shared losses near the base of a radiation may therefore become part of the geno...
