X-ray Induced Mutations in Spermatogonial Cells of Drosophila and Their Dose-frequency Relationship.
INTEREST in the mutability of spermatogonial cells has increased in recent years, primarily due to the demonstration of an X-ray intensity effect on these cells in the mouse (RUSSELL, RUSSELL, and KELLY 1958; RUSSELL 1960). Relatively few mutation experiments in Drosophila have utilized these cells compared to sperm and spermatid cells, and no large scale dose-frequency study has been carried o...
متن کاملPatient dose in routine X-ray examinations in Yazd state
Background: Medical x-rays are the largest man-made source of public exposure to ionizing radiation. It is important to avoid conditions where the amount of radiation used is more than that needed for the procedure. Materials and Methods: The Entrance Skin Exposure (ESE) measurement was conducted for quality control of x-ray machines and survey of operator’s experimental techniques. The ESEs we...
متن کاملThe frequency-dose relation of x-ray-induced y-suppressed lethals in Drosophila.
E A R L Y in radiation genetic investigations it was reported that X-ray-induced sex-linked recessive lethals were not homogeneous in composition. Instead they included: ( 1 ) apparent intragenic changes without observable cytological abnormalities (point mutations) ; (2) deficiencies; and (3) changes associated with and, for the most part, inseparable from chromosome rearrangements (OLIVER 193...
متن کاملMosaic analysis of lethal mutations in Drosophila.
The effects of various lethal mutations were studied when they were present in the hemizygous state as sectors in genetic mosaics (gynandromorphs) of Drosophila melanogaster. Sixty percent of the lethals studied can survive to adulthood in combination with normal tissue in mosaics, whereas the remainder cause the death of such mosaic animals. Some of the gynandromorph-viable lethals appeared to...
متن کاملX-ray Induced Sex-linked Lethal and Detrimental Mutations and Their Effect on the Viability of Drosophila Melanogaster.
T H E first attempts to analyze the distribution and frequency of detrimental mutations induced by radiation were made simultaneously but independently by TIMOFEEFF-RESSOVSKY ( 1935) and KERKIS (1935). They came to essentially the same conclusion: that detrimentals were induced two to three times as frequently as lethals. More recently, interest in this problem has been renewed (KFER 1952; BONN...
