Figure 1From: The identification of a spontaneous 47, XX, +21/46, XY chimeric fetus with male genitalia Autopsy and karyotypes of the chimera fetus. The aborted fetus exhibits normal external genitalia (A) and no characteristics typical of Down syndrome except the enlarged gap between the first and the second toes (B) was observed.
