  • a +/BSYy+; bw/+; Z3/(Df(3R)GC14 or +) males were crossed to C(2)EN, b pr (2^2/O) or y w (2/2) females. “C” indicates a control cross.

  • b Listed progeny are from 2^2/O crosses. bw+ and bw progeny result from 22 sperm and O eggs; b pr progeny result from O sperm and 2^2 eggs.

  • c N, number of progeny scored in 2^2 crosses.

  • d See materials and methods for procedure for estimating % NDJ.

  • e %sis-2 = % sister-chromatid NDJ/total disomic sperm = 100 × 2(bw)/(bw + bw+).
