Sex-stratified genome scans, with CIs and highlighted regions. A, Original genome scan based on all families. B and C, The genome scan for MO and FC families, respectively, shown as multicolored lines. The black line represents the sex-stratification–based 95% CI curve; the red sections of the scan curve denote regions where the LOD score exceeds the 95% CI (sex-stratification P<.05), whereas the green portions are within the CI. D, Close-up of the MO family scan in panel B for chromosome 17, with the addition of black lines that show the original genome scan (lowest curve) and the 99% and 99.9% sex-stratification CI curves (upper two curves). E, Close-up of the FC family scan in panel C for chromosome 4, with the addition of black lines that show the original genome scan (lowest curve) and the 99% and 99.9% sex-stratification CI curves (upper two curves).
