^a+/B^SYy⁺ males with the indicated third chromosomes were crossed to y w females. T16 = Df(3R)T16 (Figure 1; Gerasimova and Corces 1998), which is deficient for the entire mod(mdg4) locus.

^bSee materials and methods for procedures for inferring sperm classes from progeny phenotypes.

^cN, total number of progeny scored.

^d% NDJ = 100 × (XY + O)/N.
