Answer
Basis of differentiation
RAPD
RFLP
Definition
RAPD is a molecular marker based on random primers and PCR
RFLP is a genetic marker that relies on the generation of DNA fragments of varying lengths after DNA samples are treated with specific restriction enzymes
Time 
Is time efficient
Is comparatively less time efficient
Required sample
RAPD analysis requires only a small amount of DNA sample
RFLP analysis necessitates a larger quantity of extracted DNA
Primer
Random primers are used in DNA amplification and these primers can be utilized across different species 
Utilizes probes that are specific to particular species for hybridization 
Detection of allelic variations
RAPD cannot detect allelic variations
Can detect allelic variations 
Requirement for sequence knowledge
Does not require sequence knowledge beforehand
Requires prior sequence knowledge for probe design
Reliability
Less reliable
More reliable
Reproducibility
Exhibits low reproducibility 
Exhibits higher reproducibility
