Relationship between interval length sexual dimorphism (SDI) and relative distance from centromeres and telomeres in bighorn sheep. The location of each interval relative to centromeres (0) and telomeres (1) were inferred using the position of orthologous intervals in the domestic sheep IMF map version 4.7. The fitted curve is a second order polynomial (r2 = 0.16, quadratic term fitted in a linear model, p < 0.001).
