Chromosomal mapping of repetitive DNA and cytochrome C oxidase I sequence analysis reveal differentiation among sympatric samples of Astyanax fasciatus (Characiformes, Characidae).

abstract：:The 'centromere-from-telomere' hypothesis proposed by Villasante et al. [2007a] aims to explain the evolutionary origin of the eukaryotic chromosome. The hypothesis is based on the notion that the process of eukaryogenesis was initiated by adaptive responses of the symbiont eubacterium and its archaeal host to their n...
