From: Statistical corrections of linkage data suggest predominantly cis regulations of gene expression
Full pedigree analysis is more powerful than sibship analysis. The left panel gives the test profiles for two traits reported in Morley et al. [1]. The right panel gives the scatter plot of the scan statistics using full pedigree and sibships. For largest values of the statistics (very likely to be true positives), most of the points are above the 45° line, which suggests that full pedigree analysis provides more power than sibship analysis to detect true linkages.
