The contribution of genetic factors to ocular dominance

Ocular dominance was measured in 561 mother-father-first-born offspring triads. Some evidence was found for an effect of parental mating pattern on offspring eye dominance. Effects were strongest when a regression analysis, against the number of left-eyed parents, was conducted. Previous data also show stronger familial effects when reanalyzed using this method.Dr. Brackenridge died while this paper was in review.
