Theoretical ratio of the phenotypic correlation between relatives in a population undergoing assortative mating (AM) relative to a randomly mating (RM) population. Two types of pedigree relationships are considered: unilineal (equation 9) in panel a and descendants of fullsbibs (equation (11) in panel b. Four cases are considered: (ρ = 0.5,h2 = 0.3), (ρ = 0.5,h2 = 0.2), (ρ = 0.2,h2 = 0.3) and (ρ = 0.2,h2 = 0.2).
