Abstract
Lymphocyte cultures from female cattle in two geographic locations were used to determine the frequency of occurrence of sister chromatid exchanges on the active and inactive X chromosomes. The distribution of 129 exchanges among the two X chromosomes was not significantly different from a 1∶1 ratio.
