Abstract
The sex dimorphism for adult stature is compared in four Chilean populations which differ in their AmerIndian ABO blood group composition. Statistical analysis revealed a significant association between sex dimorphism and AmerIndian admixture in these populations. Assuming, on one hand, that sex chromosomes have an influence on adult stature and human growth and considering, on the other, that the four populations differ in their X and Y chromosome composition as a consequence of an asymmetrical inter-racial marriage practice, it is postulated that the observed association between sex dimorphism and AmerIndian gene composition is a result of this peculiar mating structure.
