PCR-restriction fragment length polymorphism (RFLP)-based analysis, also known as
cleaved amplified polymorphic sequence (CAPS), is a popular technique for genetic
analysis. It has been applied for the detection of intraspecies as well as interspecies
variation. There exist several techniques that are related with PCR-RFLP and also involve
gel electrophoresis including techniques for DNA fingerprinting and expression profiling.
This chapter describes PCR-RFLP and related techniques
