No wing phenotypes are seen in Krn27/Krn9 mutant flies.
Krn9/Krn27 is an enhancer of visible phenotype of vnL6/vn1
Krn9/Krn27 is an enhancer of wing vein L3 phenotype of vnL6/vn1
Krn27/Krn9 enhances the wing vein phenotypes seen in vnL6/vn1 mutants. A greater proportion of flies show longitudinal vein 3 loss than in vnL6/vn1 alone. The phenotype is further enhanced by one copy of spi1.
