  • Shown is the probability to detect and fine map a QTL at a 1.5% genome-wide significance level, over a range of QTL effects and numbers of F2 animals genotyped/phenotyped, and when the inbred line I has marker alleles distinguishable from all of the founders of O. Each probability is estimated from 1000 simulations of the inbred-outbred cross.
