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

An AFLP is detected as a differential mobility of an amplified DNA fragment; AFLPs, therefore, behave as codominant markers during inheritance.

Linker and/or adapter molecules can be joined to the cut ends. Linkers are short, chemically synthesized, double-stranded oligonucleotides, which contain within them one or more restriction endonuclease sites, e.g., linker 5'CCGAATTCGG (only one strand of the linker is shown here) contains one EcoRI site.

Linkers are fused with blunt-ended DNA fragments; cleavage of the linker with the appropriate restriction enzyme creates suitable cohesive protruding ends.

Linkers have the following two applications: creation of cohesive 'ends

on blunt~ended DNA fragments, and 

on fragments having unmatched or undefined sequences in their protruding ends.
