Forensic ystr

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.
