  1. 1 Power calculated as ON(0.80)/fN to account for 20% false positives included in ON.
  2. N, the total number of tests; tN, the estimated number of tests representing true null hypotheses; fN the estimated number of tests representing falsified null hypotheses (i.e., true marker-QTL linkage); PFP, the 0.20 PFP CWER P-value thresholds; oN, the observed number of marker tests that passed the significance threshold; Power, the estimated power of the test; ND, not done.
