Table 1 Partition of degrees of freedom for two loci with number of alleles n1 and n2 (a general case)

From: Models and partition of variance for quantitative trait loci with epistasis and linkage disequilibrium

Source Degrees of Freedom
additive (α) 2(n1 - 1)
dominance (δ) (n1 - 1)2
additive (β) 2(n2 - 1)
dominance (γ) (n2 - 1)2
additive × additive (αβ) 4(n1 - 1)(n2 - 1)
additive × dominance (αγ) 2(n1 - 1)(n2 - 1)2
