AN INTERSEX PIG WITH XX/XY LEUCOCYTE MOSAICISM

Abstract
A case of porcine pseudohermaphroditism is described in which the animal possessed a relatively complete but poorly developed male reporductive tract as well as the vulva and vagina of a female. Chromosome analyses showed that the animal''s leucocytes exhibited a mosaicism composed of 90% XX and 10% XY cells, whereas all previously reported cases of swine intersexuality have been genetically female.
