Genotypic (VG), genic (VA) and dominance (VD) variances of a classical random fertilizing (RF) population across the Universe of allele frequency p, for partial dominance (d=7.5 and a=10). Allogamous F₂ form subsets of this Universe in which p is equivalent to $p_{{\text{F}}_1}$ from a cross between a focal parent (with A₁ frequency p₁), and an other parent (with p₂ defined as an offset y from p₁). The values marked at p=0.5 are those of the F₂ in which the other parent is a complementary opposite to the focal parent (over all p₁); while the window between the vertical lines is the sub-Universe for all p₁ crossed with fixed p₂=½. These are actually the same variances as shown in Fig. 4, where, however, the x-axis is p₁ rather than $p_{{\text{F}}_1}$.
