D = DNA: Y = Chromosome; S = Single copy sequence. The DYS numbering scheme (e.g. DYS388, DYS390) for the Y-STR haplotype markers are controlled and administered by an international standards body called HUGO - Human Gene Nomenclature Committee - based at University College, London.
NA + chromosome + [unique DNA] egment. DYS numbers are assigned by HUGO ( Hu man enome rganization). False Paternal Event, false paternity, non-paternal event, non-paternity event: all these terms refer to a break in the Y chromosome line due to adoption, name change, "extramarital event" (infidelity), child known by other surname (mother's maiden name, stepfather's name), etc. Haplogroup (clade) usually refers to ancient/deep ancestry, before surnames
D=DNA, Y=Y chromosome, S=a unique DNA segment. A label for genetic markers on the Y chromosome. Each marker is designated by a number, according to international conventions. At present, virtually all the DYS designations are given to STR markers (a class often used in genetic genealogy).
DNA - chromosome Segment. A label for loci or genetic markers on the Y chromosome. Each marker is designated by a number, according to international conventions. Virtually all DYS designations discussed in the context of genetic genealogy are those of STR markers (which are useful for genealogy because of their relatively high mutation rate).
A designator for Y-chromosome markers. DYS stands for 'DNA Y-Chromosome Segment'.
DNA Y-chromosome Segment. The "name" of a marker on the Y-chromosome. It is assigned based on a nomenclature system controlled by the HUGO Gene Nomenclature Committee, which assigns DYS numbers to newly discovered markers.
DNA Y Segment; a number designating a given marker on the Y chromosome (e.g. DYS19, DYS390, etc.) These correspond to the headings of the tables shown here.
Acronym for NA -chromosome egment - The assigned number of a marker on a segment of the Y-chromosome. Example: DYS# 393
DYS was a straight edge hardcore punk band from Boston, Massachusetts, and part of the notorious "Boston Crew" along with contemporaries such as SSD and Negative FX. They released two LPs: Brotherhood, an album still held in high regard by fans of hardcore music, and DYS (i.e., self-titled), an album that is more a hard rock or heavy metal album than a hardcore album. In fact, "DYS" is considered by many to be (for better or worse) one of the first Crossover Thrash albums released and features what might be punk rock's first Power Ballad.
DYS is short for DNA Y-chromosome Segment, and is used to designate a segment of DNA on the Y chromosome where a sequence of nucleotides repeats. These sequences are known as short tandem repeats (STRs), and are called markers in genealogical DNA testing. The possible variations of repeats at a DYS marker are known as alleles.
