WebAug 15, 2024 · Innovations in metazoan development arise from evolutionary modification of gene regulatory networks (GRNs). We report widespread cryptic variation in the requirement for two key regulatory inputs, SKN-1/Nrf2 and MOM-2/Wnt, into the C. elegans endoderm GRN. While some natural isolates show a nearly absolute requirement for … 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 …
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 WebJan 4, 2008 · Polymorphic regulatory variation due to the Y chromosome might be expected to affect traits expressed in males. In agreement with this prediction, we found that Y-linked variation is enriched for genes that are more highly expressed in males (P < 0.0001, Kruskal-Wallis, and other similar tests below; Fig. 2A).Conversely, genes …
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 … Webvariation as direct inhibition of HSP90. These results suggest that cryptic variation played a role in the evolution of eye loss in cavefish and provide the first evidence for HSP90 as a capacitor for morphological evolution in a natural setting.
