Abstract

A dominant mutant, "Short Segment" (symbol Seg), was discovered as a spontaneous occurrence. Homozygotes and heterozygotes for Seg possess short body in length in each segment during all the larval stages. Linkage analysis showed that Seg was linked with odk and Nl, which had been mapped at the 32.5 and 35.2 positions, respectively, on the 14th linkage group. The Seg gene was precisely localized by a three-point experiment involving odk, Nl, and Seg. The recombination value between odk and Seg was calculated to be 0.60%, between Seg and NI 2.51% and between odk and Nl, 3.11%. Hence, the arrangement of these three gene loci on the chromosome is in the order odk-Seg-Nl. Taking a correction factor into account, the locus of Seg was determined to be 33.0 of the 14th linkage group.
