Two hybridizing European species of fire-bellied toads, Bombina bombina and B. variegata, have alternate electromorphs fixed at a number of allozyme loci. Segregation of alleles at seven allozyme loci (Ldh-1, Mdh-1, Ak, Ck, Gpi, Np, and Est-beta) was studied in a backross progeny of an F1 interspecific hybrid male and a B. bombina female. Mendelian inheritance of allozyme forms at all seven loci was ascertained. Except for two loci, Gpi and Est-beta, which were found to be tightly linked (1 cM apart), other loci showed independent segregation.
两种杂交的欧洲铃蟾，即欧洲铃蟾（Bombina bombina）和斑背铃蟾（B. variegata），在多个等位酶位点上具有交替的电泳变体。在一个F1种间杂交雄性与一只欧洲铃蟾雌性的回交后代中，研究了七个等位酶位点（Ldh-1、Mdh-1、Ak、Ck、Gpi、Np和Est-β）上等位基因的分离情况。确定了所有七个位点上等位酶形式的孟德尔遗传。除了发现紧密连锁（相距1厘摩）的两个位点Gpi和Est-β外，其他位点表现出独立分离。
