Examples of gametophytic selection changing $K_a/K_s$ under different selfing rates. Results are derived from equation (14) with the selection coefficients $s_h=0.03$ or 0.06 and $s_d=0$, the degree of dominance h = 0.5, the population size $N=30$, the initial frequencies $p_0=1/2N$, and the migration rates of seeds and pollen $m_S=m_P=0$.
