Contribution to the total LD of the covariance between allele frequencies component relative to the LD in gametes component. The area of each circle represents the coefficient 4 Cov(p,q)/(Dx + Dy). Filled circles represent the case in which 1/2 (Dx + Dy) > 2 Cov(p,q), while empty circles represent the case in which 1/2 (Dx + Dy) < 2 Cov(p,q). The axes of each plot are the selection coefficient in males sm (x-axis) and females sf (y-axis). Recombination rate, r, differs for each column, increasing from left to right. (a) r = 0.1; (b) r = 0.2; (c) r =0.3.
