Sex differentiation of somatic tissue in the unsexualised gonad primordia of the embryos of three species of poeciliid fish.

abstract：:This investigation is based upon the pineal organs of 92 specimens of 36 species of the family Pteropodidae (Mammalia, Chiroptera). The size of the megachiropteran pineal correlates well with body size (r = 0.864), confirming the former conclusions that generally larger bodied bats have larger pineals. The range of th...
