The exchange behavior of non-attached, whole arm, X chromosome inversions was reexamined using nondisjunction in XXY females as an indirect measure of the frequency of nonexchange tetrads. Crossing over is quite normal in these inversion heterozygotes and is independent of the arrangement of the basal heterochromatin.
