Effect of increasing the number of markers.

<p><a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0042649#s2" target="_blank">Results</a> are shown for the simulations where allele frequencies were equally distributed from 0.05 to 0.95. The number of individuals was fixed at n = 4 (left column) and n = 20 (right column). Each row contains (like in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0042649#pone-0042649-g001" target="_blank">Figure 1</a>) a different level of genetic differentiation (F_ST = 0, 0.01, 0.05, 0.1, 0.2, 0.4). The results (average F_ST and 95% CI) of each estimator are depicted in the different graphs: F_ST^W (blue circles), F_ST^C&W (purple squares) and F_ST^R (green triangles). The dashed red line indicates the actual F_ST for the simulated population.
