We have tested for the occurrence of multiple paternity in wild common shrews by karyotypic analysis and DNA-fingerprinting of five wild-caught females and their litters. Karyotypic data suggest that some litters were sired by more than one male, but provide no definitive evidence. By using DNA-fingerprinting, it was possible to establish that two males sired the litter of two females. The present report shows that multiple paternity is not a rare phenomenon in the common shrew and by using DNA-fingerprinting it is possible to assign individual offspring to different male parents even when none of the putative fathers are available for inspection.
我们通过对五只野生捕获的雌性普通鼩鼱及其幼崽进行核型分析和DNA指纹识别，来检测野生普通鼩鼱中多父本现象的发生情况。核型数据表明，一些幼崽是由不止一只雄性授精的，但没有提供确凿的证据。通过使用DNA指纹识别技术，可以确定有两只雄性为两只雌性的幼崽授精。本报告表明，多父本现象在普通鼩鼱中并非罕见现象，并且通过使用DNA指纹识别技术，即使无法检查推定的父亲，也能够将单个后代归属于不同的雄性亲本。
