Witryna28 mar 2024 · The proportion of phenotypic variance due to additive genetic variation, termed narrow-sense heritability ( h2 ), is perhaps the most fundamental aspect of a trait’s genetic architecture and... Witryna5 gru 2011 · Heritability is measured in two ways: broad-sense heritability H 2 and narrow-sense heritability h 2. Broad-sense heritability H 2 measures the full contribution of genes. It is defined as H 2 = V G / Var ( P ), where V G is the total variance due to genes.
