WebMay 11, 2024 · Introduction. 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 … WebJan 3, 2012 · Introduction.
