-
The LOD threshold determined by permutation test is ≥3.5 for significant linkage and 2.7 for suggestive linkage (the same as significant level of 1% and 5%, respectively) for a chromosome length of 100 cM.
-
↵QTLs identified previously by McBrearty et al. (1998).
-
Avg % Exp = Average (days 15, 21, and 25) percent variance explained F2 mice (70%).
