[Characteristics of meiosis in a trisomic male of the Urodele amphibian Pleurodeles waltlii Michah].
In a trisomic male the metaphases of the first and second divisions of the meiosis are analysed. Some metaphases present special aspects. They are interpreted as the result of a chromatid disjunction during the first division of the meiosos. The homology between the meiotic and mitotic chromosomes is in part completed.
