The effect of X-irradiation on the frequency of recessive lethal mutations in Drosophila melanogaster sperm cells is studied. Drosophila males were X-irradiated in air and nitrogen in three units with doses rates of 4 X 10(9), 10(11) and 1.7 rad/sec at a dose of 2000 rad. It is found that the mutation frequency after the pulse irradiation was almost twice as low as that after prolonged irradiation. The oxygen effect is eliminated under pulse irradiation, and the data on pulse irradiation in air are similar to those on irradiation at a low dose rate in nitrogen. The data obtained are explained by the presence of short-lived oxygen-dependent damages which are not realized under pulse irradiation due to the lack of oxygen in the track volume.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D012730 Sex Chromosomes The homologous chromosomes that are dissimilar in the heterogametic sex. There are the X CHROMOSOME, the Y CHROMOSOME, and the W, Z chromosomes (in animals in which the female is the heterogametic sex (the silkworm moth Bombyx mori, for example)). In such cases the W chromosome is the female-determining and the male is ZZ.

D013094 Spermatozoa Mature male germ cells derived from SPERMATIDS. As spermatids move toward the lumen of the SEMINIFEROUS TUBULES, they undergo extensive structural changes including the loss of cytoplasm, condensation of CHROMATIN into the SPERM HEAD, formation of the ACROSOME cap, the SPERM MIDPIECE and the SPERM TAIL that provides motility.
