WitrynaV P 700 [bu/acre] 2 100.0% B. What are the values of the narrow-sense heritability h 2 and of the broad-sense heritability H 2. [In estimating the broad-sense heritability, ignore any possible effects of interaction between different genes.] Recall that h2 = V A/V P and that H 2 = V G/V P: h2= 300 700 =0.428 and H2= 300+100 700 =0.571 C. WitrynaNarrow-sense heritability is defined as the fraction of phenotypic variance that can be attributed to variation in the additive effects of genes (V A): h 2 = V A / V P ⋅.
