[Quantitative dose-effect relationships of the mutagenic action of X-rays on the sex cells of the malaria mosquito Anopheles messeae].
Inseminated females of Anopheles messeae were irradiated by X-rays (1.2 and 3 kR). Estimation of mutagenic effect on the embryonic (dominant lethals) and the postembryonic (chromosomal rearrangements) stages of the development of the F1 offspring is presented. The frequency of dominant lethals varies in accordance with the dosage and the stage of maturity of oocytes. The embryonic lethality depends on induced defects of female sex cells. The frequency of chromosomal rearrangements increases to 3.2, 11.6 and 18.2%. It is suggested that the aberrations are formed by spermatozoa chromosomes, but not by those of oocytes.
