It is desirable for barcodes to show very low sequence divergence within a species, with significantly higher sequence divergence at higher taxonomic levels. The Distance Summary tool gives a report of sequence divergence between barcode sequences at the conspecific and congeneric levels.
Various distance models and alignment algorithms are available as parameters, as well as options to filter out sequences based on sequence length or sequence issues.
Comparisons are performed between the given taxonomic levels with the frequency plotted as shown below. There is one visualization provided that is normalized by species to remove sampling bias. Details for the comparisons done at the level of species, genus, and family are available by clicking on the links in the top right corner.
