Phenotype in homozygotes overlaps wild-type. cv-2k03511/Df(2R)Pu-D17 flies occasionally exhibit a disrupted anterior crossvein.
cv-2k03511/Df(2R)Pu-D17 has anterior crossvein phenotype, enhanceable by dppd6
cv-2k03511/cv-2225-3 has posterior crossvein phenotype, enhanceable by gbb4
The addition of gbb4 to cv-2225-3/cv-2k03511 animals produces an enhancement of the posterior crossvein phenotype seen in these flies. The addition of dppd6 to cv-2k03511/Df(2R)Pu-D17 animals produces an enhancement of the anterior crossvein phenotype seen in these flies.
