[Cytogenetic study of meiosis in sterile male mice].
The spermatocytes of 39 sterile males found among inbred mice were studied cytogenetically at diakinesis-metaphase I of meiosis. The chromosome aberrations: reciprocal translocation (7.7%), autosome univalents and sex chromosome dissociation were found in 17.95% of the sterile males. The fertility of 2136 males of C57BL/6 strain was estimated. The rate of sterile males was approximately 1% and frequency of spontaneous chromosome aberrations registered in MI of meiosis was 0.1%.
