Abstract
Ultrasonography can accurately determine phenotypic sex differences from those of the genetic sex. Two cases were identified; they were the result of a translocation of the SRY gene from the Y chromosome to the X chromosome during meiosis. An ultrasonographic difference may represent an otherwise unsuspected genetic abnormality.
