Detailed Description
Statement
Reference

Transforms aristae segments into tarsal segments. Heterozygotes with Ta2 exhibit the aristae to tarsal transformation and heterozygous males exhibit show an extreme reduction in the number of sex comb teeth on the prothoracic leg.

Transformation of arista to tarsus identity.

viable (but mutant) over Df(3R)Scr. Semidominant homeotic mutant that transforms aristal segments into tarsal segments. homozygous lethal Ta1/+ flies have a less extreme antennal phenotype without the reduction in the number of sex-comb teeth.

Comments

Partially complements Ta2. The heteroallelic combination Ta1/Ta2 is viable and shows transformation of the whole arista and the fourth and fifth antennal segments into a segmented tarsus with a claw at the distal end; little or no transformation of the third antennal segment; males show extreme reduction in the number of sex-comb teeth on the first leg, as in Df(3R)Scr (Kaufman et al., 1980).
