The lab has also shifted from testing genetic markers known as short tandem repeats (STRs), which are standard in paternity testing, to recording single letter variants in the genetic code known as single nucleotide polymorphisms, or SNPs, which are rarely used for this purpose.

After extracting tiny amounts of ancient DNA from the mummies» bones, the researchers amplified 16 short tandem repeats (short sequences in the DNA that create a genetic fingerprint) and eight polymorphic microsatellites (hereditary molecular markers) to testable quantities using techniques commonly employed in criminal or paternity investigations.

Metabarcoding works by comparing short genetic sequence «markers» from unidentified biological specimens to libraries of known reference sequences.

Y - chromosomes have a number of highly - polymorphic genetic markers called short tandem repeat (STRs).

Genetic studies using samples along the distribution range of both subspecies and based on a few dozen nuclear markers have revealed loci of relatively high divergence (0.3 — 1.2 %) between subspecies embedded in a genome otherwise characterized by low levels of differentiation and high levels of bidirectional gene flow [21], [24]--[26], likely facilitated by high effective population sizes, high dispersal, and a relatively short generation time [21], [24]--[26].

During sabbatical in the laboratory of Chris Tyler - Smith (Wellcome Trust Sanger Center), I genotyped the Y chromosome of HapMap samples with 16 short tandem repeat (STR) markers as well as lineage specific markers to determine whether the Y chromosome genetic information in this sample was consonant with the purported ancestry of the subjects.
