RAPD ( Random Amplified Polymorphic DNA)
RFLP : Restriction Fragment Length Polymorphism

1. Quantity of DNA required for analysis is small (10-50 ng)
2. Same primers with arbitrary sequence can be used for different species
3. Fewer steps in procedure therefore it is rapid (Five times quicker than RFLP)
4. Technique comparatively less reliable
5. Cannot detect allelic variants
6. 1-10 loci detected
7. Method involves:
1. Large quantity of purified DNA required i.e. 2-10 ug
2. Different species specific probes are required.
3. Comparatively slower processing due to more steps involved.
4. Technique comparatively more reliable
5. Can detect allelic variants
6. 1-3 loci detected
7. Method involves:
Definition: If primers with arbitrary sequences are used for amplification, DNA segments to be amplified will be selected at random and this provides truly random sample of DNA markers and so is described as random amplified polymorphic DNA (RAPD).
RFLP : Restriction Fragment Length Polymorphism
Definition: It refers to the variation in restriction fragment
lengths between individuals of a species when cut by a restriction enzyme.

7. Method involves:
a) extraction of DNA,
b) amplification by PCR using random primers,
c) gel electrophoresis of amplified DNA and visualisation of markers
