Investigations of the green frogs from western Europe for electrophoretic variations at 4 enzyme loci demonstrated a new form which must be considered as a hybrid between Rana ridibunda and R. perezi. Biochemical evidence supports the hypothesis that its reproduction is hybridogenetic, as it is for R. esculenta.
对西欧绿蛙在4个酶位点的电泳变异进行的研究表明,存在一种新的类型,它必须被视为食用蛙和泽陆蛙之间的杂交种。生化证据支持这样一种假设,即其繁殖方式是杂交起源的,就像食用蛙一样。
