WitrynaHeritability, then, is a ratio of genetic variance (V g) to total variance (V p) (i.e., h 2 = V g /V p). Total variance (or phenotypic variance) includes variance caused by genetic and environmental factors (i.e., V p = V g + V E). The numerical value of the heritability estimate is given as a percentage or a decimal and should, of course, lie ...
