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]
If x is in Z(G), then so is x −1 as, for all g in G, x −1 commutes with g: (gx = xg) ⇒ (x −1 gxx −1 = x −1 xgx −1) ⇒ (x −1 g = gx −1). Furthermore, the center of G is always an abelian and normal subgroup of G. Since all elements of Z(G) commute, it is closed under conjugation. A group homomorphism f : G → H might not ...
G-quadruplexes have been implicated in neurological disorders through two main mechanisms. The first is through expansions of G-repeats within genes that lead to the formation of G-quadruplex structures that directly cause disease, as is the case with the C9orf72 gene and amyotrophic lateral sclerosis (ALS) or frontotemporal dementia (FTD).
Viète. de Moivre. Euler. Fourier. v. t. e. In trigonometry, trigonometric identities are equalities that involve trigonometric functions and are true for every value of the occurring variables for which both sides of the equality are defined. Geometrically, these are identities involving certain functions of one or more angles.

t. e. In mathematics, function composition is an operation ∘ that takes two functions f and g, and produces a function h = g ∘ f such that h(x) = g(f(x)). In this operation, the function g is applied to the result of applying the function f to x. That is, the functions f : X → Y and g : Y → Z are composed to yield a function that maps x ...

G-banding, G banding or Giemsa banding is a technique used in cytogenetics to produce a visible karyotype by staining condensed chromosomes. It is the most common chromosome banding method. [1] It is useful for identifying genetic diseases (mainly chromosomal abnormalities ) through the photographic representation of the entire chromosome ...
