【摘要】 将非洲爪蟾胚胎细胞核移入花背蟾蜍成熟未受精卵后 ,得到了发育至各期的胚胎。对发育不同时期的胚胎 ,进行了乳酸脱氢酶同工酶谱及染色体组型分析 ,结果显示其均与受体一致。根据实验分析认为 ,非洲爪蟾的胚胎细胞核进入花背蟾蜍成熟卵后 ,引起的是花背蟾蜍的单性发育更多还原

【Abstract】 Embryos at different developmental stages are obtained by transplanting Xenopus laevis blastomere unclei to Bufo raddei unfertilized eggs. The LDH isozymes and chromosome karyotype analysis demonstrated that the nuclear tranplanted embryos exhibited the characteristics of Bufo raddei. The results show that the blastomere nuclei of Xenopus laevis induces the parthenogenesis of unfertilized egg in Bufo raddei.更多还原
