The majority of Cp190P1/Cp1903 flies die as pharate adults, with rare (2%) escapers that die shortly after hatching, and pharate adults show homeotic transformation of abdominal segment A1 into A2 (but no transformations in segments A6-A8): held out wings in escapers are often blistered, the shape of t1 (tergite of the first segment) is changed toward t2, t1 bears long bristles, inner support sclerite is absent or rudimentary, s1 (sternite of the first segment) is often visible but without bristles. Cp190P1/Cp190En15 flies show similar phenotypes to Cp190P1/Cp1903 except with slightly more escapers (5%) and s1 usually shows bristles.
CTCFGE24185, Cp190P1/Cp190En15 has partially lethal - majority die phenotype
CTCFGE24185, Cp190P1/Cp190En15 has homeotic phenotype
CTCFGE24185, Cp190P1/Cp190En15 has majority die during pharate adult stage phenotype
Cp190P1/Cp190En15 is a suppressor of wing margin phenotype of ct6
Though Cp190P1/Cp1903 or mod(mdg4)m9/mod(mdg4)GS23019 flies die as pharate adults with fully formed cuticles, Cp190P1 mod(mdg4)m9/Cp1903 mod(mdg4)GS23019 double mutant flies die as pupae (P5-7).
The majority of CTCFGE24185 Cp190En15 /CTCFGE24185 Cp190P1 double mutants die as pharate adults, with rare (2%) weak escapers that show homeotic transformation of abdominal segment A1 into A2 (less pronounced than in Cp190En15/Cp190P1) and A6-A8 (A6/7 transformations weaker than in CTCFGE24185/CTCFGE24185, though A8 transformation is enhanced): the shape of t1 is changed toward t2 though large bristles are rare, s1 usually shows no bristles, t1 bristles are more uniform than wild type; in males s6 has 0-4 (average 1) bristles, t7 is enlarged and often developed to only one side in 50% of males, t8 is well separated from t9 and usually visible with a bunch of large bristles, and genitalia is rotated 90-180[o] (100%); in females s7 has 5-11 (average 8) bristles, the shape of s7 is transformed towards s6 and bristles lose orientation, t8 always has 7-19 (average 13) large bristles (often forming two rows).
