Markov chain Monte Carlo (MCMC) run length, phenotypic mean (μ), phenotypic variance (σ2 P), residual variance(σ2 e), additive variance(σ2 A), narrow-sense heritability (h2), and the linkage groups (LG) that QTLs were mapped on.
2ln(BF). Bayes factor quantifies the support from the data for the number of QTL(s) in the model (QTL evidence), after pair-wise model comparison (1/0, 2/1, and 3/2) such as “one-QTL model” vs. “zero-QTL model. 2ln(BF)<0 = no evidence; 0–2 = hardly any; 2–5 = positive; 5–10 = strong; >10 = decisive. Bayes factor not available (na) if either model does not have enough samples in the Markov chain.
