Cryptic variation
WebApr 13, 2024 · Background Within the genus Escherichia, several monophyletic clades other than the traditionally defined species have been identified. Of these, cryptic clade I (C-I) appears to represent a subspecies of E. coli, but due to the difficulty in distinguishing it from E. coli sensu stricto, the population structure and virulence potential of C-I are unclear. … WebAug 13, 2024 · Cryptic genetic variations are recessive (not dominant) in this relationship and so under normal conditions do not show.

He further proposed that under certain environmental conditions, this property could be lost (“decanalization”), resulting in expression of the cryptic variation on which selection could act .

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 … 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 ...
