Figure 1.
The multipoint nonparametric analysis for 18q from the second-stage fine mapping using all families. The heavy solid line represents the linkage analysis using all families; the light solid line the Apolipoprotein E ε4-positive conditional linkage analysis; and the dotted line the Apolipoprotein E ε4-negative conditional linkage analysis. Map distances are based on the Marshfield genetic map. (Marshfield Medical Research Foundation, Center for Medical Genetics, http://research.marshfieldclinic.org/genetics/).
