what type of repeating dna sequence is preferred for dna fingerprinting
DNA profiling uses repetitive (repeat) sequences that are highly variable, called variable number tandem repeats (VNTRs), in particular short tandem repeats (STRs). VNTR loci are very similar between closely related humans, but are so variable that unrelated individuals are extremely unlikely to have the same VNTRs.ach personâs DNA contains two copies of these markersâone copy inherited from the father and one from the mother. Within a population, the markers at each personâs DNA location could differ in length and sometimes sequence, depending on the markers inherited from the parents.
