WebFeb 9, 2012 · Cryptic genetic variation (CGV) describes genetic diversity that is hidden within populations that occupy their native habitats but that is revealed as trait diversity within new environments ( Gibson and Dworkin, 2004; Le Rouzic and Carlborg, 2008; Schlichting, 2008; McGuigan and Sgrò, 2009 ). WebJun 1, 2011 · Cryptic variation is caused by the robustness of phenotypes to mutations 1.
