Genetic mapping information
Comments

Third-chromosome breakpoint at +34 kb; in the 15 kb overlap of Df(3R)Scx2 and Df(3R)dsx2M (Baker and Wolfner, 1988, Genes Dev. 2: 477-89; 0 point = HindIII site in αTub84D; '+' values to the right, '-' values to the left).

Does not suppress variegation of bwD.

(Talbert et al., 1994)

Heterozygotes with stk and hat mutations exhibit a partial eclosion phenotype.

(Cavener et al., 1986)

homozygous lethal When heterozygous with Ta2, the translocation is viable and shows a transformation of the whole arista and antennal segments four and five into tarsus and, in males, an extreme reduction in number of sex-comb teeth on the first leg (Kaufman et al., 1980). With mutant alleles of hat and stk gives rise to the same lethal 'partial eclosion' phenotype (Cavener et al., 1986).

"position-effect variegation for: stk" was stated as tentative. "position-effect variegation for: hat" was stated as tentative. Mutant for both stk and hat, but molecular data do not indicate a deletion; presumably a position-effect.
