Which of the following statements about quantitative genetics is TRUE? 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.

The phenotype is the observable and measurable characteristics of an organism as a result of the interaction of the genes of the organism, environmental factors, and random variation.
