	RFLP
		Restriction fragment length polymorphism (RFLP); the acronym is pronounced "riflip".
		Restriction fragment length polymorphism is the identification of specific restriction enzymes that reveal a pattern difference between the DNA fragment sizes in individual organisms.
		RFLP is most suited to studies at the intraspecific level or among closely related taxa.

		RFLP analyses have been widely used in the medical field to identify DNA fingerprints specific for inherited diseases or other genetic loci [336,311,252].
		RFLP analyses allow the observance of genetic variation in organisms within defined regions of the genome due to DNA rearrangements or mutations which affect recognition sites for restriction endonucleases.
		The RFLP pattern is highly distinctive for each type, and can be used to unambiguously assign an unknown sample to a pathovar, using simple visual comparisons of pattern against a set of known samples, such as those given in Figure 6-5.

	RFLP Definition (Site not responding. Last check: 2007-10-29)
		Restriction Fragment Length Polymorphism (RFLP) is a technique in which organisms may be differentiated by analysis of patterns derived from cleavage of their DNA.
		If two organisms differ in the distance between sites of cleavage of a particular restriction endonuclease, the length of the fragments produced will differ when the DNA is digested with a restriction enzyme.
		Isolation of sufficient DNA for RFLP analysis is time-consuming and labor intensive.

	The Classes of Molecular Markers
		RFLP markers have several advantages in comparison with the RAPD and isozyme markers: 1) they are codominant and unaffected by the environment; 2) any source DNA can be used for the analysis; and 3) many markers can be mapped in a population that is not stressed by the effects of phenotypic mutations.
		RFLP analysis is an application of the Southern hybridization procedure.
		For RFLP mapping, you first need to determine the clone/restriction enzyme combinations that are polymorphic between the parents of your mapping population.

	Notes On Paternity Testing
		RFLP is an older DNA analysis technique that has been in use for a number of years.
		A minor disadvantage of the RFLP method is that it is slightly slower to produce results than PCR; it takes 10 to 14 days to properly process a DNA sample using RFLP analysis.
		The RFLP technique has been in use for a long time and is widely recognized as scientifically valid.

	How RFLPs Can Help Find a Faulty Gene
		RFLPs give geneticists another view of human inheritance: Not only can they track the passage of physical traits or disease through a family, but they can follow the course of genetic material itself by tracking riflips through generations - that is, if they have DNA from all the family members.
		So if a RFLP nearly always accompanies a disease in a particular family, the gene for this disease must be fairly close to it.
		Linkage studies of this sort depend on the mother's RFLPs being different from the father's, and on the family being sufficiently large.

		Entries that have identical (or probably identical) RFLP patterns, except for one or two lanes that were not scored, have been pooled into a single consensus line.
		While this streamlined version of the RFLP maps no doubt contains errors, it is hoped and anticipated that the errors in this shortened version will be less problematic than the errors caused by gene conversions or scoring errors.
		An on-line RFLP mapping program for the first cross was developed to facilitate placement of new loci; this program is available through the Neurospora Genome Project HomePage (http://www.unm.edu/~ngp/).
