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 … 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...

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. A longstanding question in evolutionary biology is the extent to which selection acts on pre-
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 … 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 …
WebEarth’s biodiversity is in trouble. Global changes, from habitat loss and invasive species to anthropogenic climate change, have initiated the sixth great mass extinction event in Earth’s history. Conservation management is compromised by the absence of information on species presence or absence, abundance, ecology, and biogeography and has a … WebThe fact that cryptic variation can form the basis for genetic changes in the mean values of quantitative traits has already been elegantly demonstrated by Cooper . He showed that artificial selection on cryptic genetic variation for flowering time, which had been exposed by an environmental change in seed vernalization conditions, resulted in ...
WebAug 26, 2008 · The discovery of a prevalent cryptic genetic diversity within species of planktonic foraminifera and other fossil-producing plankton (e.g., ref. 18) implies that evolutionary patterns extracted from fossil microplankton may represent the development of a cohort of cryptic sibling species.
WebJan 1, 2008 · the currently invisible (cryptic) genetic variation that has the potential to influence the evolutionary properties of a quantitative trait.
