Sports pairs: Insights on athletic talent; research reviews: Twins with leukemia; parents and twins

Abstract

Twin research exploring genetic and environmental influences on athletic interests and talents is reviewed. Illustrative examples of twin athletes representing a variety of sports activities are presented. This is followed by an overview of twin studies offering critical insights into the onset and progress of leukemia. In the last section, timely events involving twins and parents of twins will be described - each case provides a new look at an old question.
