From: Multiallelic models for QTL mapping in diverse polyploid populations
Example of QTL interval detection. p value distributions are shown for the same region in the same population using the three models (left, SNP; middle, IBD and right, haplotype). Detected QTLs are presented above each plot for three values of l: 1, 3 and 5 cM. Horizontal red dotted lines represent the permutation threshold for each model, and grey vertical lines highlight the true QTL position. In the SNP model with l = 1 cM, three QTL intervals are detected, of which only one contains the true QTL position, while with higher values of l, only one QTL interval is detected. In the IBD and haplotype models, a single true QTL is detected for all l values shown
