Table 1 Ordered genotypes with their respective population genotype frequencies, number of B-alleles (gene count), breeding values (BVs) as father and as mother and parent-of-origin effects (POEs). The allele frequencies of B and b are denoted by p and q = 1 − p. The parameters α and i are the allele-substitution effect and the imprinting effect.
