Cryptic genetic variation
WebThe amount and distribution of cryptic genetic variation will, in turn, determine the likelihood that cryptic variants, once expressed, will be adaptive or maladaptive during environmental transitions. We then present specific approaches for measuring these parameters in natural populations. Finally, we discuss one natural system that will be ... WebOct 28, 2003 · Cryptic genetic variation is genetic variation for phenotypes not observed under most conditions. However, given specific environmental or genetic backgrounds, phenotypes can be sensitized so as to express phenotypic variation, and this variation has been demonstrated to possess an underlying genetic basis 3, 4, 5.
