Abstract excerpt
The SSU nrDNA (18S), is one of the most frequently sequenced molecular markers in phylogenetic studies. However, the length-hyper-variation at multiple positions of this gene can affect the accuracy of alignment greatly and this length variation makes alignment across arthropod orders a serious problem. The analyses of Hexapoda phylogeny is such a case. A more clear recognition of the distribution of the...
