variation in the lengths of restriction fragments of DNA. These fragments are obtained from different individuals due to genetic polymorphism of the restriction sites in the chromosomes. It is also known as DNA fingerprinting.
(RFLP) A heritable difference in DNA fragment length and fragment number; passed from generation to generation in a codominant way.
Variation in DNA sequence between individuals that is detectable by variation in the length of DNA fragments generated by digestion with restriction endonucleases.
