title: [Invariability of the H-Y antigen expression in the heterogametic sex of some amphbians and evidence for sexual dimophrism of the antigen expression in Pelodytes punctatus D (Amphibia, Anura)].
abstract: The H-Y antigen is studied in some Amphibians whose sexual genetic constitution is known. Thus, in Pelurodeles waltlii, Ambystoma mexicanum, Xenopus laevis and Rana ridibunda, the invariability of the H-Y antigen expression in the heterogametic, sex is confirmed. In Pelodytes punctatus the genetic sex is unknown but the existence of the H-Y antigen in phenotypic males leads to the conclusion of a male heterogamety of the XY type.
