Environmental influence on the phenotype: Morphological variation in human dentitionThis work is about the role that environment plays in the production of evolutionary significant variations. It starts with an historical introduction about the concept of variation and the role of environment in its ...
Several case-control studies have demonstrated that a predominance of small, dense LDL (LDL subclass phenotype B) is associated with increased risk of coronary heart disease (CHD). Phenotype B is also consistently characterized by an atherogenic lipoprotein phenotype, including increased levels of ...
Moreover, our results suggest that selection previously operated on caste phenotype in this species, and phenotypic variation is now governed primarily by environmental differences.

As these examples illustrate, there are many specific instances of environmental influences on gene expression. However, it is important to keep in mind that there is a very complexinteractionbetween our genes and our environment that defines ourphenotypeand who we are. References and Recommended Rea...
Phenotype is defined as the physical, physiologic, and behavioral traits of an individual produced by the interaction of the genetic makeup and environmental influences. From: Journal of Allergy and Clinical Immunology, 2009 About this pageAdd to MendeleySet alert ...
These data suggest that expression of the phenotype typical of domesticated gerbils requires deprivation of a variety of stimuli normally experienced by burrow-dwellers during ontogeny. 展开 关键词: Behavior Development Endocrine morphology Gerbils Dark rearing Domestication ...
There are marked variations in PR3-ANCA:MPO-ANCA and GPA:MPA incidence ratios with latitude, which further supports the potential effect of an environmental influence on disease phenotype. UV radiation has been postulated as a potential latitude-sensitive factor, due to its strong inverse correlation...
Environmental canalization is defined as a reduction in the effect of external environmental perturbations on a phenotype, while phenotypic plasticity is defined as the production of different phenotypes in alternative environments. These terms describe different aspects of the same phenomenon, that is, th...
The significant influence of environment on the dormancy phenotype makes this trait an obvious target for marker-assisted-selection. Closely related breeding lines, SUN325B and QT7475, containing a major dormancy QTL derived from AUS1408 located on chromosome 4A, but substantially different in ...
For example, heritability – i.e., the percentage of total variance explained by genetic variance – of height may not, be constant but dependent on the magnitude of environmental variation influencing the phenotype21. A poorer household environment may more often than a more affluent one, fail ...
