and it may be sensitive to reproducible results. This is typically due to the conditions in which it was produced. RAPD's are used also under the assumption that two samples share a same locus when a sample is produced. Different markers may also require different amounts of DNA. RAPD's may only need 0.02 ug of DNA while an RFLP marker may require 10 ug of DNA extracted from it to produce identifiable results. currently, SNP markers have turned out to be a potential tool in breeding programs in several crops.
