[Studies of localization of black streak body gene in Drosophila melanogaster].

Mutation type of body color shows frequently yellow (y), black (b) and ebony (e) in Drosophila melanogaster and locates on X, second and third chromosom respectively. A mutant of black streak (bsr) is a spontaneous mutation strain building in the laboratory in 1991. Whether this mutation strain is rediscovered on the primary style or not. We have discussed this problem with general cross breeding and complementation test. The result of complementation test indicated that it is a mutant in first filial generation with trans heterozygote and that it is few wild in second filial generation with cis teterozygote due to crossing over in crossing bsr and e. But, we believe that bsr and e is located same loci (93D2) but not the same sites. This report discussed for correlation inter-gene body color and ruleless of heredity passing down for black streak body.
