Allele Frequencies of Three STRs in an Italian Population Sample
Several short tandem repeat (STR) (1) polymorphisms have been recently described which are potentially useful in procedures of criminal identification and in paternity tests. STRs consist of short DNA stretches arranged in 2–6 base pair long tandem repeats. They are abundant in the human genome and generally are highly polymorphic. Because of their small size (generally 300 bp) STRs are more likely to be investigated from degraded DNA samples. Tetranucleotide-repeat microsatellites are of primary interest, because they are more easily genotyped.
