title: Human meiosis: model organisms address the maternal age effect.
abstract: Studies in Drosophila support the view that a failure of cohesion between sister chromatids may contribute to meiotic nondisjunction in humans. Moreover, the demonstration of a meiotic aneugen in mice provides important clues to the higher frequencies of nondisjunction observed in older women.
