Cryptic or hidden genetic variation is a type of genetic variation normally not seen but can, as has been shown experimentally in many species, emerge from polymorphisms changing their effects upon genetic (G-by-G interaction; Epistasis) [1–3] or environmental (G-by-E interaction) [4–7] perturbations.The release of …

WebFeb 5, 2024 · Cryptic genetic variation has been shown to play an important role in evolution because genetically diverse populations are more likely to contain genotypes with a ‘pre-adapted’ phenotype, for example, a latent promiscuous function, that may confer an immediate selective advantage when the environment changes and a new selection … WebWhat is cryptic genetic variation? Cryptic genetic variation refers to unexpressed, bottled-up genetic potential. It is not normally seen, but is expressed under abnormal conditions such as in a new environment or a different genetic background.
