在日本鳗鲡（Anguilla japonica，n= 51）和日本鳗鲡（Anguilla）的玻璃期至银期个体中发现了雄激素受体基因（ar5）内含子的种特异性限制性片段长度多态性。大理石纹（n= 21）。对采集于北太平洋西部北赤道流海域的328个鳗类标本进行16S rDNA序列分析，结果表明：A. japonica（n= 194），A. marmorata（n= 128）、花斑拟步行虫A. bicolorpacifica（n= 5）和A. luzonensis（n= 1）。A. japonica和A. marmorata是单态的，在ar5位点上没有共享等位基因，表明这两个物种是生殖隔离的。
Species‐specific restriction fragment length polymorphism in the intron of the androgen receptor gene (ar5) was found in glass to silver‐stage individuals ofAnguilla japonica(n= 51) andA. marmorata(n= 21). The sequence analysis of 16S rDNA from 328 anguillid leptocephali collected in the North Equatorial Current of the western North Pacific Ocean revealed the specimens to beA. japonica(n= 194),A. marmorata(n= 128),A. bicolorpacifica(n= 5) andA. luzonensis(n= 1). All leptocephali ofA. japonicaandA. marmoratawere monomorphic and did not share an allele at thear5locus, indicating that the two species are reproductively isolated.
