  • Full genotype of crosses: C(1)M4/Y; Dp(1;2)v+75d, Hmr+ v+/+ females crossed to males indicated in column 1.

  • a Dead males were scored in these crosses; duplication and nonduplication genotypes could not be distinguished.

  • b 14 dead eclosed, 40 dead pharate.

  • c 7 dead eclosed, 88 dead pharate.

  • d 0 dead eclosed, 13 dead pharate.

  • e 1 dead eclosed, 3 dead pharate.
