Polytene chromosomes normal.
Amino acid replacement: C655S.
Nucleotide substitution: T1344C.
The mutant allele contains the nucleotide polymorphism G1964C, which results in a C655S protein polymorphism. It also contains the silent nucleotide polymorphism T1344C (coordinates of the lesions are the position in the 2-μ-4a spliced form of pb).
Nucleotide substitution: G1964C.
The labial palp is transformed to prothoracic leg.
