title: Chemical control of breathing in identical twin athletes.
abstract: Studies in identical twin athletes, using a wide range of methods of measuring chemical control of breathing, have demonstrated identity of ventilatory responses to hypoxia and hypercapnia in such subjects. This suggests that, when the effect of a major environmental factor, physical activity, is removed, genetic factors predominate in determining the ventilatory responses to carbon dioxide and hypoxia.
