Linkage analyses of ECB21 on chromosome 4. Linkage results for three MCMC approaches (A-C) and 5 marker panels: STRPs only (black dots in A or dotted line in B-C), AFFY_0.3 (thick purple line), STRPs plus AFFY_0.3 (thin green line), ILMN_1.5 (red dashes and dots), and AFFY_1.5 (blue dashes). (A) Negative log10 of the p-values for Spairs for ECB21_D. (B) LOD scores for ECB21_Q. (C) Bayes factors for ECB21_Q. Numbers and tick markers on the top axis denote STRPs and their positions.
