a
This P element carries a wild-type copy of the ry gene. The distance between the insertion site (82A1-2) and the rosy gene was measured when P{ry+t7.2=PZ}abs00620 ry506/T(2;3) females were crossed to ry/ry males. Approximately two-thirds of this interval is distal to 85A-C and not expected to be affected by proximal translocations.
b
This P element carries a white mini-gene. This was used as a marker to measure crossing over between the insertion site (83A4-6) and cu when w/w; P{w+mC=lacW}ksrj5E2 cu/T(2;3) females were crossed to w/Y; cu/cu males.
