Figure 2.

Linkage disequilibrium and its components for various recombination frequencies and selective strengths. LD is represented by the area of the circle at any given point (s_m, s_f) in the parameter space. The axes of each plot are the selection coefficient in males s_m (x-axis) and females s_f (y-axis). Recombination rate, r, differs for each column, increasing from left to right. (a) Average LD in gametes 1/2 (D_x + D_y). (b) Twice covariance between allele frequencies, 2 Cov(p,q). (c) Total LD, D_t, in zygotes.
