Abstract
Our theoretical framework for quantitative inheritance is now complete. The phenotypic value for any individual is caused by its genotype and its environment. The genotypic effect can be subdivided into additive effects of genes; dominance deviations, interactions between effects of genes at the same locus; and epistatic interactions between effects of genes at different loci. Individuals differ in all three of these factors, so that the variance of phenotypic values is caused by additive, dominance, epistatic, and environmental variance components; the first three of these, taken together, constitute the genotypic variance. Since they relate to the factors that actually cause variation, they can be termed the causal factors of phenotypic variance.
