A quantitative geneticist determines the following variance components for leaf width in a population of wildflowersgrowing along a roadside in Kentucky:Additive genetic variance (VA)=4.2Dominance genetic variance (VD)=L6Interaction genetic variance (M)=O.3Environmental variance (VE)=27Genetice-environmental variance (I/GIE)=0.03. Calculate the broad-sense heritability and the narrow-sense heritability for leaf width in this population of wildflowers.b. What do the heritabilities obtained in (3) indicate about the genetic nature of leaf width variation in this plant?
