Heritability is the measure of the proportion of an individual's phenotype that is due to genetics. QTL mapping provides an overestimate of the number of genes contributing to a quantitative trait. A threshold trait is measured in whole numbers. An H2 value (broad-sense heritability) that approaches 0.0 means that almost all the phenotypic variation is determined by genetic differences. The h2 (narrow-sense heritability) value is a prediction of the impact that selection may have in altering an initial population by artificial selection.arrow_forward
