  • a Males carrying wild-type fourth chromosomes were crossed to C(4)RM ci eyR (4^4/O) females. GC14 = Df(3R)GC14 (93D7; 93E1). T16 = Df(3R)T16 (93D7; 93D9). Both Dfs are deleted for the mod(mdg4) locus. C, control cross.

  • b ci ey progeny result from union of O sperm with reciprocal 4^4-bearing eggs; all other sperm classes yield ++ progeny.

  • c % 4-loss = 100 × (ci ey progeny)/N.
