Outline of Final Research Achievements

This study constructed an analysis pipeline to identify marker genes from genomic data for phylogenetic studies of ray-finned fishes. The pipeline was developed by implementing cutting-edge methods of molecular phylogenetics and by analyzing all protein-coding gene sequences of 15 vertebrates. Genome structural comparisons among vertebrates suggest that common structure of teleost genomes were established just after whole genome duplication occurred in the ancestor of all extant teleosts.
