Figure 5. Within-group estimates of relatedness (R) for female-female, female-male, and male-male dyads.

Observed mean within-group R (solid line) and simulated means (gray area) with 95% CI (dotted lines). Graphs are shown for female-female, female-male, and male-male dyads in three groups (BS, SP, and WW group). The simulated groups consist of randomly drawn dyads of any sex combination from the same group.
