title: The effect of X-irradiation on the fertility and on the induction of meiotic chromosome rearrangements in mice and their first generation.
abstract: The effect of whole-body or local irradiation with X-rays at a dose of 600 R on the induction of chromosomal translocations in the diakinesis metaphase I of the meiosis in treated and F1 males has been examined along with their fertility. Our results show the high percentage of mortality in whole-body irradiated mice. The percentage of the fertility was 25% in whole-body, and 93.7% in locally irradiated males. The testis weight was also reduced. The percentage of chromosomal translocations in diakinesis, metaphase I, or the meiosis was higher after whole-body irradiation than after local irradiation. In F1 males both types of irradiation induced chromosomal translocations.
