WitrynaGenetic variance is a concept outlined by the English biologist and statistician Ronald Fisher in his fundamental theorem of natural selection.In his 1930 book The Genetical Theory of Natural Selection, Fisher postulates that the rate of change of biological fitness can be calculated by the genetic variance of the fitness itself. Fisher tried to give a … Witryna22 gru 2015 · where g ∼ N(0, VgA) is a random vector of genetic contributions to the phenotypes, Vg = Pσ2 is the variance of total additive genetic effects, and A = ZZT / P is the GRM between pairs of individuals. GCTA obtains maximum-likelihood estimates (MLEs) of the parameters α2 and Vg and then estimates the heritability as the ratio … WitrynaHeritability estimate of 12.03% was recorded for grain yield. Akber et al. (2008) reported high heritability estimate (82%) for grain yield.
