Abstract
An adult male house muck shrew with an XXY sex chromosome constitution was found in a laboratory-bred colony. Maternal origin of the additional X chromosome was demonstrated. The external appearance of the animal was normal, but the testes were small and displayed a high density of interstitial cells. The seminiferous tubules were narrow and contained only Sertoli cells.
摘要
在一个实验室饲养的种群中发现了一只具有XXY性染色体组成的成年雄性家鼩鼱。额外X染色体的母源起源得到了证实。该动物的外观正常，但睾丸较小，间质细胞密度较高。生精小管狭窄，仅含有支持细胞。
