Power of QTL detection 1- β ^∗ of joint composite interval mapping model 1 with cofactor selection method 1 for different numbers of QTLs (25, 50, 100) and different heritabilities (0.5, 0.8) at different α ^∗ levels in a scenario of 29 backcross nested association mapping (BC-NAM) subpopulations. Colors indicate combinations of different number of QTLs and heritabilities. Vertical lines at each point indicate the standard errors
