Abstract
The genetically inactivated X-chromosome in subfertile cows carrying a n X-autosome translocation was determined. Identification was by compa rative measurement of the sizes of the Barr body and the drumstick, in the translocation carriers as well as in the control (normal) of cows , and by autoradiography. The normal X-chromosome of the translocation carriers was found to be subject to preferential genetic inactivation . The biological significance of this observation is discussed in rela tion to previous cases of X-autosome translocation in man and the mous e.
