J.  aCytogenetic study of intersex swine.h[electronic resource]  c1990  aTo clarify the etiology of intersexuality due to genetic factors, 33 intersex swine and 33 of their ascendants were studied karyotypically. Metaphases were obtained from peripheral blood lymphocytes and analyzed by chromosome G and C banding in addition 10 standard Giemsa staining. Two cases of chromosome anomalies were observed: an intersex presenting 38,XX/38,XY mosaicism or chimerism, and an intersex presenting a break in one chromosome of pair 9, with a karyotype identical to that of the remaining intersex animals, i.e., 38,XX. All parents had normal karyotypes, i.e., 38,XX for females and 38,XY for males. Macro- and microscopic examinations of the genitalia of 26 of the 33 intersex animals revealed that 10 were true hermaphrodites, 14 were male pseudohermaphrodites and two were morphologically normal females except for a slightly hypertrophied clitoris and a "parrot beak"-shaped vulva.  acytogenetics  aswine  aCitogenética  aSuíno  aAnomalias  aAnomaly1 aFERRARI, I.1 aSCHEID, I.
