Cryptic variation
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 ... WebJan 1, 2008 · the currently invisible (cryptic) genetic variation that has the potential to influence the evolutionary properties of a quantitative trait. When potentially adaptive cryptic variation is accumulating, the population is charging, whereas the release of formerly hidden variability in response to selection corresponds to a discharge event.

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 … 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. In a sense, the measurable component of normal variation is just the tip of an iceberg
Webvariation as direct inhibition of HSP90.
