Combined STR and SNP linkage analysis of derived phenotypes and EEG principal component phenotype. SIBPAL linkage analysis on chromosome 2 using combined STR and SNP data. Outcome variables for the first five graphs are phenotypes derived from Alc1 (DSM-III-R criterion of alcoholism) or Alc2 (DSM-IV criterion of alcoholism) and latent variable 1, 2, 7, 9, or 11. Results from phenotypes derived from Alc1 are graphed as solid lines; those derived from Alc2 are graphed as dotted lines. Outcome variable for the last graph is the first principal component calculated from all 13 EEG (electrophysiological) variables. Y-axis is the value of the Haseman-Elston regression coefficient. Significant values are indicated with circles.
