The genome-wide 2logBFs profiles of scanning loci (A) and genetic effects (B) obtained with Bayesian model selection for body weights in mice. The horizontal reference line is the critical 2lnBF value of 2.1 for the significance test. The genome consists of 19 linkage groups that are separated by the vertical dotted lines. The 19 linkage groups are drawn to scale and proportional to their chromosomal lengths. Positions of the markers are indicated by the ticks on the horizontal axis. The thick solid, dashed and thin solid lines represent additive, dominance and imprinting effects, respectively.
