WebThe accumulation of cryptic genetic variation by canalization may therefore increase evolvability at the population level by leading to phenotypic diversification under decanalizing conditions. On the other hand, under canalizing conditions, a major part of the segregating genetic variation may remain phenotypically cryptic; canalization may ...
WebJul 26, 2024 · ryptic genetic variation is standing ge-netic variation that does not normally contribute to heritable phenotypic var-iation in a population but that can bring forth phenotypic variation after environmental change or genetic perturba-tion (1, 2). Cryptic variation exists because phenotypes are to some extent robust to ge-netic change (3–6).
