All TRFs are listed using the code: (dye)(length in bp).
TRFs unique to that species and definable on analysis.
TRFs combined into a single bin due to lack of distinction on analysis.
TRFs combined into a single bin due to lack of distinction on analysis.
UTRF: TRF derived from the upstream i.e. forward primer end of the amplicon.
DTRF: TRF derived from the downstream i.e. reverse primer end of the amplicon.
