Abstract
Spadefoot toads of the subgenus Scaphiopus have two isocitrate dehydrogenase loci, with no intergenic interaction between them. Toads of the subgenus Spea have three Idh loci, with intergenic enzymes formed between two of them, providing strong evidence for their homology and the origin of one through a duplication process. The Idh phenotype of interspecific hybrids is consistent with the theory of a gene duplication.
摘要
铲足蟾亚属Scaphiopus的蟾蜍有两个异柠檬酸脱氢酶基因座，它们之间没有基因间相互作用。Spea亚属的蟾蜍有三个异柠檬酸脱氢酶（Idh）基因座，其中两个之间形成了基因间酶，为它们的同源性以及其中一个通过复制过程的起源提供了有力证据。种间杂种的Idh表型与基因复制理论一致。
