Simulated genetic architecture of traits T1, T2, and T3, as dictated by QTL Q1, Q2, Q3, Q4, and Q5.

a Scenario S0 is for type I error evaluation. Scenarios SI, SII and SIII are for model fitting evaluations.

b Heritability (%) due to all QTL affecting a trait.

c General mean of each trait.

d Main effect of QTL. The percentage of phenotypic variation of each trait due to each QTL is 5%.

e Position, in cM, of the QTL from the leftmost marker in the chromosome (Chr).

f Residual variance-covariance matrix.
