Zusammenfassung

Autoradiographische Untersuchungen mit H3-Thymidin deckten bei der WühlmausA. scherman exitus (2n = 36) eine ungewöhnliche Geschlechtschromosomensituation auf. DasX-Chromosom misst 6,8% von (nA + X). Sein funktioneller Anteil ist zweigeteilt, daneben verfügt es über einen strukturell heterochromatischen und einen stets euchromatisch bleibenden Anteil. DasY ist für ein Säugetier aussergewöhnlich gross (2/3 desX).
