Nondisjunction rates were measured by crossing wild-type females to y cv v f car/BSY males under standard conditions, which allowed identification of nondisjunctional progeny as multiply-marked males (XO) or BS females (XXY). The numbers in parentheses are the standard deviations of the X nondisjunction rates. The lines marked with * have significantly different nondisjunction rates when compared to MW9X.
