Modifiers of Tumorous Head Genes in Natural Populations and Laboratory Stocks of Drosophila Melanogaster.
نویسندگان
چکیده
HE tumorous head (tu-h) abnormality and genetic mechanism were disTcussed by GARDNER (1948), GARDNER and WOOLF (1949) and NEWBY ( 1949). Penetrance, expressivity and relative viability were investigated by GARDNER and RATTY (1952). The influence of high and low temperatures on the expression was described by GARDNER and WOOLF (1950). Modifiers and alleles of tumorous head genes were found in laboratory stocks by GARDNER and WOOLF (1949) and GARDNER and STOTT (1951). The purpose of the present paper is to report the results of experiments designed to determine the presence, nature and frequency of modifiers for the tumorous head genes in natural populations and laboratory stocks.

Further evidence for maternal effect and modifiers of tumorous head genes in natural populations of Drosophila melanogaster.
An inherited abnormality (Figs. 1-9), consisting of irregular growths of various sizes in the head region of the tuk strain of Drosophila, is under investigation. The strain was obtained from Dr. Wilson Stone and appeared in 1945 in a culture of flies obtained at Acahuizotla, Mexico, in 1941 by a collecting party from the University of Texas. Two interacting genes, tu-1 in the first chromosome ...
متن کاملViability of homokaryotypes in the tumorous-head strain of Drosophila melanogaster.
HE tumorous-head trait in Drosophila melanogaster is caused by a third chromosome gene (tu-?) showing reduced penetrance. The penetrance can be increased by a sex-linked recessive gene ( tuI ) controlling a maternal effect (GARDNER and WOOLF 1949), by polygenic modifiers (GARDNER, STOTT and DEARDEN 1952), and by high temperature during an early developmental period (GARDNER and WOOLF 1950). Whe...
متن کاملEffect of laboratory acclimation on the variation of reproduction-related characters in Drosophila melanogaster.
The natural variation of sex-specific characters between populations can favor their behavioral isolation, eventually leading to the formation of new species. Marked variations for male courtship, mating and the production of sex pheromones - three complex characters potentially inducing sexual isolation - were found between Drosophila melanogaster populations of various origins acclimated for ...
متن کاملThe Relation between Expressivity and Selection against Eyeless in Drosophila Melanogaster.
ANY mutant stocks of Drosophila mass cultured in the laboratory for generaM tions become phenotypically almost indistinguishable from wild type. Upon outcrossing, the mutant reappears in the FZ with its pristine strength of expression. Presumably, genes reducing the degree of expression, or expressivity, of the major character of the mutant stock had appeared and accumulated through natural sel...

Background: In this study, the toxicity of the different xenobiotics was tested on the fruit fly Drosophila melanogaster model system. Methods: Fly larvae were raised on food supplemented with xenobioticsat different concentrations (sodium nitroprusside (0.1-1.5 mM), S-nitrosoglutathione (0.5-4 mM), and potassium ferrocyanide (1 mM)). Emergence of flies, food intake by larvae, and pupation h...
