WebSep 29, 2024 · The genetic variance ( V G ) can be further subdivided into three types, i.e., (1) additive genetic variance, (2) dominance variance, and (3) epistatic variance. Additive genetic variance occurs due to genes which show an additive effect on the quantitative trait. This results in deviance from the mean phenotype due to inheritance of a ...

WebPhenotypic Variation. Phenotypic variation is an important adaptive mechanism in rotifers, but has posed difficult problems for systematists. This variation arises by several mechanisms including cyclomorphosis, dietary- and predatorinduced polymorphisms, polymorphisms in hatchlings from resting eggs, and dwarfism. 表現型の可塑性（ひょうげんがたのかそせい、表現型可塑性）とは、生物個体がその表現型を環境条件に応じて変化させる能力のことである 。 この言葉は同じ遺伝子型でも表現型が異なる場合を指し 、遺伝子型の違いによって複数の表現型が見られる場合（すなわち、遺伝的多型）は含まない。なお、表現型可塑性によって生じる多型の事をpolyphenismと呼ぶ 。表現型可塑性は、形態的にはっきりと区別できる不連続な違い …
