| genetic structure of a japanese allotetraploid loach of the genus cobitis (osteichthyes, cobitidae). | the japanese allotetraploid spined loach of the genus cobitis "yamato complex" sensu saitoh et al. (2000), distributed in western japan, originated from hybridization between c. biwae on the maternal side and c. striata (kyushu form) on the paternal side. mitochondrial (mt) and nuclear dna were analyzed in order to determine the genetic relationships among 15 populations spanning the entire range of the yamato complex. pcr-rflp analysis of the nd1 mtdna gene indicated that the yamato complex con ... | 2003 | 15303347 |
