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.
