(redirected from additive genetic variance)

additive

In foods, any of various chemical substances added to produce desirable effects. Additives include such substances as artificial or natural colourings and flavourings; stabilizers, emulsifiers, and thickeners; preservatives and humectants (moisture-retainers); and supplementary nutrients. Though many additives are harmless or even beneficial, others reduce nutritional value or conceal inferior raw materials or processing.

(mathematics)additive - A function f : X -> Y is additive if

for all Z <= X f (lub Z) = lub { f z : z in Z }

(f "preserves lubs"). All additive functions defined over cpos are continuous.

("<=" is written in LaTeX as \subseteq, "lub" as \sqcup ).

Narrow sense heritability was estimated as the proportion of additive genetic variance to total variance as follows, where the terms are the variance components for the terms in the earlier mentioned model:

Thus, selective breeding and domestication efforts that emphasize selection on additive genetic variance should be effective, and our data provide no reason to believe that more complicated breeding schemes designed to use nonadditive heterotic effects, whatever the mechanism, would be advantageous over the judicious selection or construction of a base population with low inbreeding depression.

05); therefore even when growth rates differed significantly among environments, the additive genetic variance did not vary from location to location, with the exception of Putemtln and Hueihue for live weight and shell height respectively.
