Chemical induction of nondisjunction in drosophila.

Abstract

Tests for chemically induced nondisjunction and loss of the sex chromosomes in Drosophila were performed. Of 31 compounds tested four gave rise only to an increase of XO exceptions, indicating the induction of chromosome loss. Six compounds, all known spindle inhibitors (colchicine, organic mercury, lead, and tin compounds) gave rise to an increase both of… (More)
