*a*Males carrying the attached-XY chromosome*Y*(symbolized^{S}X.Y^{L}, In(1)EN, y B*X^Y*) and one copy of each of the indicated mini-X chromosomes were crossed singly with two females carrying the attached-X chromosome*C(1)RM, y*(symbolized^{2}*X^X*).↵

*b*Disjunction of the Dp from the X^Y results in X^X/Dp (y+) females and X^Y/O (y B) males. Dp-X^Y nondisjunction gives rise to X^X/O (y^{2}) females and X^Y/Dp (y^{+}B) males.↵

*c**N*, total progeny scored.↵

*d*NDJ = (y^{2}females + y^{+}B males − 0.5(1 −*T*)*N*)/*NT*. (Values of*T*are from Table 1). Asterisks indicate the level of significance of the χ^{2}test for the difference between observed NDJ and NDJ = 0.5. **P*< 0.05; ***P*< 0.01.
