In a double-blind, double-matched population survey, the tremor of 12 XYY, 14 XXY, and 52 XY men were studied clinically and by a special tremor recording equipment. XYY men were found to have a more pronounced tremor than XY normals, while XXY men were not found to differ in any definite way from normal XY men.
