^a[CR-7.5] is a P-element transgene containing a 7.5-kb genomic DNA fragment encompassing all of the common region of mod(mdg4) (Buchner et al. 2000).

^b+/B^SYy⁺ males carrying the indicated autosomes were crossed to y w females and X–Y NDJ measured as described in materials and methods.

^cN, total progeny scored.
