re·stric·tion frag·ment length pol·y·mor·phism (RFLP),
used in genetic analysis of populations or individual relationships. In regions of the human genome not coding for proteins, the distance (in nucleotides on the chromosome) can be different between two genetic markers, usually because of repeated base patterns.
restriction fragment length polymorphism (RFLP)
a difference in the DNA sequences of homologous chromosomes as revealed by different lengths of the restriction fragments produced by enzymatic digestion of a selected region of chromosomes. RFLPs are believed to be inherited according to mendelian laws and have been used to locate the genes associated with several inherited disorders, including Huntington's disease.
re·stric·tion frag·ment length pol·y·mor·phism(RFLP) (rĕ-strik'shŭn frag'mĕnt length pol'ē-mōrf'izm)
Used in genetic analysis of populations or individual relationships. In regions of the human genome not coding for proteins there is often wide (but measurable) sequence variety between people.
