Insertion of a 1.2kb P-element 69bp upstream of the y transcription start site, together with deletion of y sequence from -146bp to -70bp. The P-element is internally deleted, containing 829bp of 5' sequence and 347bp of 3' sequence, with the filler sequence TAGCTACAAA in between. The P-element is transcribed in the same orientation as that of the y gene.
Body colour: yTDH-1491/y2sA3 flies have a pigmentation score of 1 in the wing and 3 in the body (where 1 = absence of y expression and 5 = wild type). Body colour: yTDH-1583/y2sA3 flies have a pigmentation score of 1 in the wing and 3-4 in the body. Body colour: yTDH-1683/y2sA3 flies have a pigmentation score of 2 in the wing and 3-4 in the body. Body colour: yTDH-1872/y2sA3 flies have a pigmentation score of 3 in the wing and 4 in the body. Body colour: yTDH-1924/y2sA3 flies have a pigmentation score of 3 in the wing and 5 in the body. Body colour: yTDH-2097/y2sA3 flies have a pigmentation score of 4-5 in the wing and 5 in the body. Body colour: yTDH-641/y2sA3 flies have a pigmentation score of 1 in both the wing and body. Body colour: yTDH-786/y2sA3 flies have a pigmentation score of 1 in both the wing and body.
Body colour: pigmentation of the body and wings is reduced, pigmentation of thoracic, leg, wing and abdominal bristles is normal.
