Predicted male frequency versus inbreeding depression.
K values slightly below (K = 2.5) or above (K = 3.5) the estimated K value (K = 2.9) based on the observed number of flowers in male and female trees were used. Three selfing rates (s = 0.1, 0.2, and 0.5) were chosen. The observed frequency of male trees in the population was 32.14%.
