Étude cytologique d'une translocation chromosomeY-autosome chez la souris

A male mouse with one translocation involving theY-chromosome has been observed in the F1 offspring of a male mouse given 300 R of X-irradiation. 6 types of spermatocytes were recorded. Our observations appear to confirm that the acrocentricX of the mouse associates end-to-end with theY at its centromeric end.
