Abstract: AbstractDNA methylation is an important epigenetic mechanism involved in many biological processes, i.e. gametogenesis and embryonic development. However, increased copy numbers of DNA methylation related genes (dnmt, tet and tdg) have been found during chordate evolution due to successive whole genome duplication (WGD) events. Their evolutionary history and phylogenetic relationships remain unclear. The present study is the first to clarify the evolutionary history of DNA methylation genes in chordates. In particular, our results highlight the...
