Statement: AFLP shares some features of both RFLP and RAPD analyses.

Explanations: I. It uses restriction enzyme-digested genomic DNA as template for PCR amplification using primers that contain the restriction enzyme recognition sites plus a number of, usually 2-3, arbitrary nucleotides.

II. AFLPs are faster, less labour intensive and provide more information than RFLPs, and they are highly reproducible, which is a great advantage over RAPDs.

The lakes of northern Minnesota are home to many similar species of damselflies of the genus Enallagma. These species have apparently undergone speciation from ancestral stock since the last glacial retreat about 10 thousand years ago. Sequencing which of the following would probably be most useful in sorting out evolutionary relationships among these closely related species?
