Deletion of transcription unit.
2kb deletion in the 5' region that encodes the embryo specific transcription unit.
Tracheal metameres in remaining 5 abdominal segments develop many aspects of a wild type branching pattern. Phenotype is much less disrupted than that of Df(3L)ri-XT1, where both kni and knrl are deleted.
SNS is normal.
Defective in gonad assembly.
Abdominal segments A1 to 7 are fused andreplaced by a single segment, segment 8 is normal.
Strong phenotype.
kni8 has embryonic abdominal segment phenotype, suppressible by Res1r1
kni8 has embryonic abdominal segment phenotype, non-suppressible by Res1r2
kni8 has embryonic abdominal segment phenotype, non-suppressible by Res1r3
Strong kni allele.
