Multipoint quantitative linkage analysis of BMI in Campora. Multipoint quantitative linkage analysis of BMI in Campora. A: LOD of the regression-based quantitative trait linkage approach of Sham et al. (14) over the whole genome. Chromosomes are ordered and delimited by vertical dashed lines. B: Estimated posterior probabilities (lFDR) of linkage with BMI in Campora, along the 22 chromosomes, expressed as −log10(lFDR). The dashed line corresponds to a 5% threshold for the lFDR.
