Heterozygotes show an incomplete or deleted anterior crossvein in 5% of wings.
vnC221/vn1 transheterozygotes are viable and display deletions of the anterior crossvein and a portion of wing vein L4 proximal to the posterior crossvein. vnC221/vnddd-13 transheterozygotes are semi-viable at 25oC, escapers survive for 3 days and are of normal appearance except for held-out wings and the absence of anterior cross vein.

One copy of vnC221 enhances the reduction in wing blade area seen in homozygous sl2 males.
One copy of vnC221 partially suppresses the ectopic wing vein phenotype seen in sl2 homozygotes.
One copy of vnC221 partially suppresses the percentage of sl2 mutant ommatidia that contain extra R7 photoreceptors.
The loss of wing vein L4 which is seen in vn1/vnC221 animals is rescued by Bap170hfl1/+ in 90% of cases.
The presence of a vnC221 background causes minor suppression of ectopic wing vein formation found in cswY279C.Scer\UAS (Scer\GAL4tub) mutants.
