【Abstract】 The karyotypes of Kansu wapiti (Cervus canadensis macneilli),Java sambar (Cervus timoriensis timoriensis),northeastern wapiti (Cervus canadensis xqnthopygus),and Japanese sika deer (Cervus nippon nippon) in Beijing Zoo were investigated by the method of hemoculture.The chromosome number of Kansu wapiti,Manchurian wapiti and Japanese sika deer was found to be 2n = 68.All of them had 2 metaeentric and 64 acrooentrie autosomes.Their X chromosome appeared to be the largest acrocen-tric,the Y chromosome of Kansu wapiti and northeastern wapiti to be the smallest submetacentric and that of sika deer was also the smallest one but its centric region could not be identified.The Java sambar appeared to have a chromosome number of 2n = 60.10 metaeentric and 48 acrocentric autosomes were observed.The X chromosome of this species was the largest actocentrie and the Y chromosome appeared to be one of the smallest acrocentrics and was not easily identified.更多还原
