Gene–environment interaction (or genotype–environment interaction or G×E) is when two different genotypes respond to environmental variation in different ways. A norm of reaction is a graph that shows the relationship between genes and environmental factors when phenotypic differences are continuous. [ 1 ]
Gene–environment interaction occurs when genetic factors and environmental factors interact to produce an outcome that cannot be explained by either factor alone. [6] For example, a study found that individuals carrying the genetic variant 5-HTT (the short copy) that encodes the serotonin transporter were at a higher risk of developing depression when exposed to adverse childhood experiences ...
The Talking Glossary of Genetics is a science learning tool developed by the National Human Genome Research Institute (NHGRI) at the National Institutes of Health (NIH). NHGRI oversaw the NIH's role in the Human Genome Project, the international research effort aimed at mapping the genes in the human body and developing tools for gene discovery.
Environmental epigenetics is a branch of epigenetics that studies the influence of external environmental factors on the gene expression of a developing embryo. [1] The way that genes are expressed may be passed down from parent to offspring through epigenetic modifications, although environmental influences do not alter the genome itself.
From position and maternal effects on gene expression to epigenetic inheritance [6] to the active construction and intergenerational transmission of enduring niches, [3] development systems theory argues that not only inheritance but evolution as a whole can be understood only by taking into account a far wider range of ‘reproducers’ or ...
The interactions of genes with environment, called gene–environment interactions, are another component of the nature–nurture debate. A classic example of gene–environment interaction is the ability of a diet low in the amino acid phenylalanine to partially suppress the genetic disease phenylketonuria.
Data structure of gene and protein data in Wikidata is a bit complex. Even if there is only one gene/protein article in Wikipedia, there are many data pages in Wikidata. Basically Wikidata has distinct pages for gene and protein each, for respective species (See the table below). And pages are interconnected based on following rules.
In the development of the lung a bronchus branches into bronchioles forming the respiratory tree. [21] The branching is a result of the tip of each bronchiolar tube bifurcating, and the process of branching morphogenesis forms the bronchi, bronchioles, and ultimately the alveoli.
