Induction of Dominant Lethal Effects by X-Radiation in Habrobracon.
ULLER in 1927 stated that the “partial sterility” of X-rayed males M of Drosophila wasdue,at least to an appreciable extent, to dominant lethal changes induced in the sperm. It was impossible, however, to determine whether the eggs were actually “fertilized.” In Drosophila the result would be the same; the eggs would fail to develop, whether dominant lethals were induced or the sperm were inact...
متن کاملThe Induction of Recessive Lethals in Drosophila Oocytes.
ORK on recessive lethal mutation in Drosophila sperm has suggested ways win which chromosome breakage may be related to recessive lethal mutation, through position effect, deficiency, and as a direct result of breakage. The increase in aged oocytes of radiation-induced dominant lethals (PARKER 1959) and of rearrangement, the slower rejoining of breaks (PARKER and HAMMOND 1958) , and the higher ...
متن کاملChemical induction of dominant lethals in female mice.
N female mammals, reduction in the number of live embryos following preI fertilization treatment with chemical mutagens could be due to genetic damage or to the interference by the agent with normal oogenesis, ovulation, fertilization, or maternal physiology. Such factors, which make dominant-lethal induction studies in adult female mammals difficult, have been dealt with in detail (RUSSELL 196...
متن کاملThe Induction of Recessive Lethals in Drosophila Melanogaster by Radiations of Different Ion Density.
ARLY investigators in radiation genetics claimed that X-rays of different wave E lengths, gamma rays, and beta particles of radium were equally effective in inducing sex-linked recessive mutations in Drosophila melanogaster and that densely ionizing radiations such as recoil protons from neutrons and alpha particles were less efficient than the less densely ionizing X, gamma, and beta radiation...
