^‡D, component of variation due to additive effect of genes; H₁, component of variation due to dominance effects of genes; H₂, dominance component indicating asymmetry of positive and negative effects of genes; F, relative frequency of dominant and recessive alleles in the parents; E, environmental variation; W_r, covariance between families within the ith array and their nonrecurrent parent; V_r, the variance among family (F₁ + reciprocal) means within an array; Y_r, mean parental value.
