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.

幼鼠嵌合体的雌雄同体现象。
在23只5日龄小鼠嵌合体中,有11只为性嵌合体。其中4只雌雄同体,6只雄性,1只雌性。在三种雌雄同体的性腺中,卵巢组织的碎片非常小。卵母细胞不仅在卵泡中生长,而且在睾丸中也有生长。讨论了卵泡卵向睾丸转化的过程。
