| Abstract |
|
Sternotherus Pelomedusa Kinosternon Emys Pseudemys Terrapene Chinemys Cuora Testudinidae Platysternon H-Y antigen was investigated in 14 turtle species belonging to five different families. In 13 species the female was typed as H-Y antigen positive, only in Chinemys reevesi was the male H-Y antigen positive. Since in all vertebrate species studied till now, the expression of H-Y antigen is strictly correlated with the heterogametic sex, it can be assumed that in turtles both types of sex determining mechanisms are realized, namely the ZZ/ZW-and the XX/XY mechanism; both mechanisms are realized in species belonging to one and the same turtle family. However, most turtle species seem to be endowed with a ZZ/ZW sex determining mechanism. Added by: Admin Last edited by: Beate Pfau |
