Cryptic variation
WebJan 3, 2012 · Introduction. Many developmental systems produce outputs that are insensitive to a wide range of environmental or genetic perturbations. In these robust systems, buffering may allow for the accumulation of “cryptic” genetic variation affecting the system without changing its end product –.Upon major environmental or genetic … WebMar 11, 2014 · Cryptic genetic variation (CGV) is genetic variation that normally has little or no effect on phenotype but that, under atypical conditions that were rare in the history of a population, generates...

WebJul 26, 2024 · Cryptic genetic variation can facilitate adaptation in evolving populations. To elucidate the underlying genetic mechanisms, we used directed evolution in Escherichia coli to accumulate variation in populations of yellow fluorescent proteins and then evolved these proteins toward the new phenotype of green fluorescence. Populations with cryptic … WebJan 10, 2024 · Developmental plasticity of plant root systems has been the subject of intensive research, but the mechanisms underpinning robustness remain unclear. Here, we show that potassium deficiency inhibits lateral root organogenesis by delaying early stages in the formation of lateral root primordia.

Thus, meiotic chromosome pairing is, surprisingly, discriminated among homologous chromosomes with cryptic sequence variation associated with different inbred lines. …
WebApr 11, 2024 · Here, we use a comparative approach to investigate how pattern use varies across a phylogeny of 268 species of cryptic and aposematic butterfly larvae, which also vary in social behaviour. We find that longitudinal stripes are used more frequently by cryptic larvae and that patterns putatively linked to crypsis are more likely to be used by ...
WebJul 26, 2024 · Cryptic genetic variation is standing genetic variation that does not normally contribute to heritable phenotypic variation in a population but that can bring forth phenotypic variation after environmental change or genetic perturbation (1, 2).
