Comparison of sexual dimorphism (SDI) in interval length between orthologous bighorn sheep and domestic sheep intervals. 192 intervals between adjacent markers were compared (reduced major axis regression, y = 0.95 × + 0.42, r2 = 0.21, 95% CI = 0.09, 0.37). SDI values are positive when intervals are larger in females and negative when intervals are larger in males.
