Plot of genome-scan data on 371 markers, using four diagnostic criteria and two sets of allele frequencies. The MLS for each marker is plotted for allele frequencies in the Swedish control population (A) and in the pedigree (B). Each panel includes one plot for each of the four diagnostic categories used (four plots per panel): Scz, SAD, Brd1, and Brd2. The plotted values for the LOD scores >3 are indicated by an arrow and the marker name. The scale for each chromosome reflects the number of markers typed, rather than the size of the chromosome.
