Abstract
The frequency of monosomy X in cytogenetically abnormal abortion material (10% to 15%) suggests that viable 45,X subjects might have covert mosaicism for X or Y cell lines. The deoxyribonucleic acid samples from seven 45,X subjects with Turner syndrome were examined with three Y-specific deoxyribonucleic acid probes. Successive hybridizations with each of these three sensitive deoxyribonucleic acid probes did not reveal any Y-specific band.
