Y-Chromosome short tandem repeat, typing technology, locus information and allele frequency in different population: A review

MA Kareem, AO Hussein, IH Hameed


Chromosome Y microsatellites seem to be ideal markers to delineate differences between human populations. They are transmitted in uniparental and they are very sensitive for genetic drift. This review will highlight the importance of the Y- Chromosome as a tool for tracing human evolution and describes some details of Y-chromosomal short tandem repeat (STR) analysis. Among them are: microsatellites, amplification using polymerase chain reaction (PCR) of STRs, separation and detection and advantages of X-chromosomal microsatellites.

Key words: Forensic, population, review, STR, Y- chromosome.
