  1. For the values of α (the strength of selection) and σ Y (the standard deviation of the quantitative trait per unit time) considered here, the power and localization distance (in DNA base pairs) are comparable for QBlossoc and LSS in the case of six subpopulations. (Population divergence times for the six subpopulations are omitted for simplicity. See text for details).
