These are presumed to be more affected by early androgen exposure than traits that are not sex-specific.
We were able to use the same advanced intercross population for both acute (E1) and repeated alcohol exposure (E2) traits, because of the significant phenotypic correlation between the E1 and E2 phenotypes, with extreme lines being in common between the two traits.
As is typical of the symptoms associated with psilocybin mushroom ingestion, "the effect on mood in particular is dependent on the subject's pre-exposure personality traits", and "identical doses of psilocybin may have widely differing effects in different individuals".
We found that cardiovascular responses to drug exposure were trait-, drug-, and dose-specific.
As in RCTs, groups defined by genotype will experience an on-average difference in exposure to trait A, whilst not differing with respect to confounding factors.
In the case of cancer, substantial evidence shows that the carcinogenic process is a multistage process driven by the interaction of exogenous carcinogenic exposures, genetic traits, and other endogenous factors.
However, in striking contrast, cocaine exposure in trait impulsive rats has the dramatic effect of decreasing impulsivity (Dalley et al., 2007), an effect that might be mediated by a restoration of dopaminergic function in the ventral striatum of this group of animals (D.C., Y. Hong, B.J., B. Everitt, T. Robbins, T. Fryer and J.W.D., unpublished findings).
Traditionally, analyzing gene-environment interactions has been extremely challenging, and this is primarily because the low relative frequencies of the exposures and/or trait have limited the study's statistical power [ 32].
These methods were applied to Anthyllis cytisoides L., a semi-arid environment shrub, to ascertain the effect of grazing and slope exposure on developmental traits in a 2×2 factorial design.
This form of exposure reproduces neuropathological traits of Alzheimer Disease.
