Comparative frequency of x-ray induced crossover-suppressing aberrations recovered from oocytes and sperm of Drosophila melanogaster.
incidence of dominant lethality is of the same order of magnitude in T z c y t e s as in sperm of Drosophila melanogaster given the same radiation exposure ( SONNENBLICK 1940; BATEMAN and CHANDLEY 1963). However, when oocytes of females bearing free X chromosomes are irradiated, the frequency of X-ray induced translocations is only 1/100 of that recovered from sperm given the same X-ray exposur...
متن کاملTemperature sensitivity of negative segregation distortion in Drosophila melanogaster.
Previous work has shown that the direction of segregation distortion in the SD (Segregation Distorter) system in Drosophila melanogaster can sometimes be reversed, but this was found only with rather weak distorters and the effect was not large. The present study reports large negative segregation distortion in a strong distorter, SD-72 chromosome. In the presence of a specific X chromosome, su...
متن کاملThe Effect of Carbon Monoxide as a Respiratory Inhibitor on the Production of Dominant Lethal Mutations by X-Rays in Drosophila.
HE modifying influence of carbon monoxide on the extent of X-ray-induced Tgenetic damage in Drosophila has been studied in the past by HAAS, DUDGEON, CLAYTON and STONE (1954); STONE, HAAS, ALEXANDER and CLAYTON (1954); ALEXANDER and STONE (1955) ; FRITZ-NIGGLI ( 1959) ; CHANG, WILSON and STONE (1959) ; and OSTER (1959). Irradiation, delivered in an environment of carbon monoxide, with or withou...
متن کاملI-44: Mutagenesis during Embryogenesis
We developed several novel tools to genome wide screen for CNVs and SNPs in single cells. When applied to cleavage stage embryos from young fertile couples we discovered, unexpectedly, an extremely high incidence of chromosomal instability, a hallmark of tumorigenesis (Vanneste et al., Nature Medicine, 2009; Vanneste et al., Hum.Reprod., 2011). Not only mosaicisms for whole chromosome aneuploid...
متن کاملDetermination of hemolysis, osmotic fragility and fluorescence anisotropy on irradiated red blood cells as a function of kV of medical diagnostic X-rays
Background: People occasionally undergo medical diagnostic X-ray examinations and expose their red blood cells to radiation. Radiation that is generated from medical diagnostic X-ray machines is widely used in medical diagnoses. One of the important parameters is kilo-voltage (kV) that is applied across the X-ray tube in medical diagnostic X-ray machines. Kilo-voltage influences the radiation d...
