【摘要】 本项工作对湖北钉螺指名亚种三个地理种群的酯酶等8种酶进行了等位基因电泳图象的比较研究。结果表明8种酶系统在钉螺三个地理种群内均具有活性,表现11个基因位点。三种群间遗传距离(D)分别为0.005432,0.015428和0.005686。更多还原

【Abstract】 Eight enzymes (eleven loci) of three populations of Oncomelania hupensis hupensis were investigated by means of starch gel electrophoresis. 3 loci (IDHP, α-GPDH, and EST-1) were single in band and monomorphic. 8 loci(GOT,PGI,XDH,HBDH-1 HBDH-2EST-2 EST-3 PGM) were polymorphic. Nei’s genetic distances between every two populations were 0. 005432, 0. 015428 and 0. 005686 respectively, showing the genetic stability of O. hupensis hupensis as a subspecies.更多还原
