Abstract

3 protogynous hermaphrodites were found in a domesticated strain of Xiphophorus helleri, confirming much doubted observations by older authors. It therefore seems that sex determination may vary between strains, certain strains being strictly gonochoristic but others being capable of true hermaphroditism.

摘要

在剑尾鱼的一个驯化品系中发现了3只雌性先熟雌雄同体，证实了早期作者备受质疑的观察结果。因此，性别决定似乎可能因品系而异，某些品系严格为雌雄异体，但其他品系则能够真正进行雌雄同体生殖。
