tna1/tna5 larvae do not have melanotic tumors, nor are they larger in size than wild type.

65% of tna1/tna5 animals reach third instar larval stage, but only 41% pupate, and only 8% of the expected number reach pharate stage. No tna1/tna5 animals eclose as adults. The tna1/tna5 third instar larvae that fail to pupate often survive long after the pupation of their heterozygous siblings. The lifespan of some of the tna1/tna5 larvae extends to at least two weeks. In contrast to wild-type late stage third instar larvae, tna1/tna5 continue feeding.

tna1/+ flies show a slight held-out wing phenotype.

17% of heterozygotes have a held-out wing phenotype.

tna1/tnarI075, tna1/tnaS058302 and tna1/tnaL6731 flies can have a partial transformation of haltere to wing. 17% of heterozygous flies have a held-out wings phenotype. tna1/tnarI075, tna1/tnaS058302 and tna1/tnaL6731 flies show a reduction in the number of sex combs on the first leg. tna1/Df(3L)lxd6 animals dervied from tna1 homozygous female germline clones (these animals lack both maternal and zygotic tna function) generally die as third instar larvae, although a few animals reach the pharate adult stage. These pharate animals have fewer sex comb teeth in the male first legs than normal and show a haltere to wing transformation. tna1/+ animals derived from tna1 homozygous female germline clones (these animals lack maternal but not zygotic tna function) develop to normal, fertile adults.

Trans-heterozygous tna1, osa1 double mutants show a stronger held-out wing phenotype than either of the single mutants.

smt304493/+ enhances both the penetrance and expressivity of the held-out wing phenotype of tna1/+ flies. A maternal effect is observed in the enhancement of the tna1/+ held out phenotype by smt304493/+.

lwr4-3/+ enhances both the penetrance and expressivity of the held-out wing phenotype of tna1/+ flies.

lwr13/+ enhances both the penetrance and expressivity of the held-out wing phenotype of tna1/+ flies.

γTub23CPl-2 results in a held-out wing phenotype in double heterozygous combination with tna1 (75% penetrance).

100% of brm2/tna1 flies have a held-out wings phenotype. 65% of tna1/Glut4EFAntp-R flies have a held-out wings phenotype. 75% of Glut4EFAntp-B/tna1 flies have a held-out wings phenotype. 100% of tna1/osa1 flies have a held-out wings phenotype. 100% of tara2/tna1 flies have a held-out wings phenotype. 87% of tara20/tna1 flies have a held-out wings phenotype. 80% of tara03881/tna1 flies have a held-out wings phenotype. tna1 does not show a strong genetic interaction with Snr10319, kto1, MED17s2956, ash21, trx1, trx00347, urd2 or sls1.
