Genetic research to evaluate plus stutter on D18S51 locus

The PCR amplification of STR loci typically produces a minor byproduct called minus stutter (or plus stutter) that is one repeat unit shorter longer) than the original product. These stutters cause some problems affect result typing and complicate when comparing results typing. It necessary to remove in forensic Minus filtered out automatically by setting analysis software. On other hand, at most Kits does not have such it particular difficult distinguish between peak peak.
