Intersex Modifying Genes in Wild Strains of Drosophila Melanogaster.
HE sex determining mechanism in diploid Drosophila melanogaster is T completely stable. No intersexual individuals are produced from hybridizing strains of D. melanogaster collected from widely separated geographical localities. In Lymantria, on the contrary, GOLDSCHMIDT (1934) has shown that the potencies of the X chromosome sex gene differs in races from Europe and Japan. The degree of sexual...
متن کاملEffects of SR-spirochete infection on Drosophila melanogaster carrying intersex genes.
Three sex-transforming genes (ix, tra-D, and dsx) in D. melanogaster were examined with respect to possible interactions with the NSR strain SR-spirochetes. The SR-spirochetes exerted a lethal effect on XY but not on XX individuals, regardless of whether they were phenotypically males, intersexes, or females. These results, taken together with those reported by Sakaguchi and Poulson (1963)on tr...
متن کاملLongevity in Some Wild Type and Hybrid Strains of Drosophila melanogaster
It is known that aging is a multifactorial mechanism composed of both genetic and environmental components. The main evolutionary theories of aging are antagonistic pleiotropy and mutation accumulation, neither of which has substantial experimental support yet. In this study, the longevities of three wild type strains of Drosophila melanogaster and F1 hybrids derived from them were determined. ...
متن کاملModifying expression of the engrailed gene of Drosophila melanogaster.
The engrailed gene is required for segmentation of the Drosophila embryo and is expressed in cells constituting the posterior developmental compartments. In mutant embryos lacking engrailed function, portions of the cuticular pattern in each segment are deleted, resulting in fusion of adjacent denticle bands. Using P-element-mediated transposition, we generated flies that express the engrailed ...
