Lesion mapped to: 24-28 kb.
Slight transformation of adult second abdominal tergite to the first.
Transformation of A2 towards A1 is weaker than in abd-Aiab2-K, a mild transformation is seen in hemizygous flies. A1 tergite shows some large bristles indicative of transformation towards a more posterior segment. Transheterozygous combinations with abd-Aiab2-Uab1 display no detectable effect on A2.
Homozygous viable, causes a partial transformation of the adult second abdominal segment into the first.
Heterozygotes with abd-Aiab2-K exhibit transformation of abdominal segment 2 to segment 1 identity.
abd-Aiab2-S3 has phenotype, enhanceable by su(Hw)2
