title: Mechanisms of nondisjunction induction in drosophila oocytes.
abstract: Quantitative and qualitative studies on the induction of no-disjunction and related phenomena can be carried out using the germ cells of Drosophila. X-Irradiation breaks chromosomes and cold-shock disrupts spindles, these two treatments producing different spectra of nondisjunction in oocytes.
