Polytene chromosomes normal.
gly --> glu (Gaul, Redemann and Jackle, 1989)
Weak segmentation phenotype. Malpighian tubules are shorter than normal in homozygous embryos (the posterior tubules are longer than the anterior tubules), with irregular buds. The zigzag pattern of nuclei is disturbed. The ureter is more or less normal.
Weak allele. Segments T2, T3, A1 and A2 are deleted.
Segments T2 and 3 and A1 deleted; A2-4 variably deleted Malpighian tubules short.
Weak allele.
