| 摘 要： | 通过长期观察、试验和研究认为，性成熟的棕色田鼠与双亲或雌亲相处或与兄妹鼠相处都不能发情，从而体现亲缘关系对棕色田鼠发情所具有的明显抑制作用。同母喂养的非同胞异性鼠相处能够动情，说明遗传识别在棕色田鼠亲缘识别中起重要作用。非同母喂养的非同胞异性鼠和同母喂养的异性非同胞鼠中的雄性睾丸下降率显大于异性同胞鼠相处时的雄鼠，说明亲缘关系对雄性睾丸下降表现出明显的抑制作用。

| Abstract: | Through observing vaginal cytology of female mandarin voles paired with different males in different conditions, females paired with male nonsiblings that were reared apart displayed vaginal estrus. In contrast, females paired with male siblings showed little estrous smear. Females paired with nonsiblings that were reared together display vaginal estrus, too. Descendness rates of testis in male paired with nonsibling females that were reared together or apart are higher than that of males paired with female siblings that were reared by same parents. This shows that genetic relationship may retard or holdback estrous of female and male in mandarin voles and both familiarity and phenotype are two most likely mechanisms for recognizing kin and inbreeding avoidance. |
