Result of the multipoint linkage analysis of seven ocular and nasal traits. (A) ex-ex, (B) en-en, (C) en-ex, (D) ps-pi, (E) al-al, (F) n-sn, and (G) sn-prn. All traits were adjusted for significant covariates identified among age, sex, age*sex, age2, age2*sex, height, weight and BMI. The x-axis represents 22 autosomes (sequentially), and the y-axis depicts empirically adjusted LOD scores for all graphs.
