Genetic analysis of mutant chromosomes 3 with similar phenotypic effect from geographically distant populations of Drosophila melanogaster
- Institute of Cytology and Genetics, Novosibirsk (Russian Federation)
From geographically distant populations of Drosophila melanogaster, the following mutant phenotypes with a wide spectrum of similar phenotypic variation were isolated: {number_sign}89300 and {number_sign}89386 from a population of Uman` (Ukraine) in 1989, and {number_sign}920017, {number_sign}921314, and {number_sign}921503 from a population of Gorno-Altaisk (Altai) in 1992. A similar mutant phenotype (line {number_sign}i13) was obtained by {gamma}-irradiation of the laboratory line Canton S. Phenotypic changes involve eye shape and structure, morphology of body appendages (wings, legs, and antennae), and fertility. Genetic analysis of mutations {number_sign}89300 and {number_sign}89386 showed that they belong to the third linkage group. Chromosomes 3 of mutants {number_sign}89300 and {number_sign}89386 carry inversions In(3R)92D-98F and In(3R)89F-95A, respectively. A complementation test for allelism of the isolated mutations among themselves and with several laboratory lines was conducted. The mutant phenotypical effect of the chromosomes isolated is assumed to be related to geographic variants of alleles of two closely linked genes, rotund and roughened eye and claret. 10 refs., 1 fig., 2 tabs.
