title: Hermaphroditism in young mouse chimeras.
abstract: Among 23 5-day old mouse chimeras, 11 were sex chimeras. Four of them were hermaphrodites, six were males and one was female. In the gonads of three hermaphrodites fragments of ovarian tissue were very small. Growing oocytes were observed not only in ovotestes but also in testes. The course of transformation of ovotestes into testes is discussed.
