Statement: In a modified version of AFLP, the selection of fragments using biotin-streptavidin binding is avoided.

Explanations: I. The fragments are ligated to the appropriate adapters and used for PCR amplification using two AFLP primers, each primer having a single selection nucleotide; this is called preamplification step.

II. The PCR products from this preamplificated step are diluted and used as template for second PCR amplification.
