Unresolved orthology and peculiar coding sequence properties of lamprey genes: the KCNA gene family as test case
Abstract Background In understanding the evolutionary process of vertebrates, cyclostomes (hagfishes and lamprey) occupy crucial positions.Resolving molecular phylogenetic relationships of cyclostome genes with gnathostomes (jawed vertebrates) genes is indispensable in deciphering both the species tree and gene trees.However, molecular phylogenetic
