A Y-STR is a short tandem repeat (STR) on the Y-chromosome. Y-STRs are often used in forensics, paternity, and genealogical DNA testing. Y-STRs are taken specifically from the male Y chromosome. These Y-STRs provide a weaker analysis than autosomal STRs because the Y chromosome is only found in … See more Y-STRs are assigned names by the HUGO gene nomenclature committee (HGNC). Some testing companies have different formats for the way STR markers are written. For example, the marker DYS455 may be written as … See more Forensic databases (without individual information, for frequency purposes): • US Y-STR Database • Y Chromosome Haplotype Reference Database See more • List of Y-STR markers • Tandem repeat • Genealogical DNA test See more There are regions on DNA that are made up of multiple copies of short repeating sequences of bases (for example TATT) which repeat a … See more In the United States, 13 different autosomal STR loci are used as a basis of analysis for forensic purposes. If crime scene DNA is ample and all 13 autosomal loci accessible, the likelihood of two unrelated people matching the same sample is around … See more Diagrams • National Institute of Standards and Technology (NIST) — Y STR Positions along Y Chromosome See more WebY-chromosome-specific human DNA markers can be a useful tool in forensic casework. Several case scenarios are presented to point out the advantages and disadvantages of Y-STR testing over autosomal STR testing. The main advantage of the Y-STR approach is the ability to detect the male component even …

WebThe following databases allow DNA labs to search and estimate the Y-STR haplotype frequency across populations for forensic and paternity casework. Yfiler™ and Yfiler™ Plus kits are engineered for >99.99% concordance to facilitate upgrade between the two kits and maximum usage of available Y-STR databases.

This position would ignore the fact that regardless of population distinctions, observing an extended Y STR haplotype (12-17 loci) is a rare event in any of the major population groups routinely considered for forensic analyses.
