The number one reason people use Y-chromosome 26 STR Analysis, is to reconstruct family linked relationships, and prove or disprove genealogical research (ie. family trees). This test is used to support or disprove a direct male-to-male linkage between 2 male participants.
Designed for comparing male descendants of a common male ancestor, the Y-chromosome test (or surname test) is especially helpful in determining how closely two males may be related in a directly paternal lineage.
An analysis to find a Most Recent Common Ancestor (MRCA) is possible using a combination of researched genealogies, Y-STR DNA test results, and statistical formulas. GeneTree is offering the cutting edge of high-tech genealogical research.
Y-chromosome markers provide researchers (i.e., forensic scientists, evolutionary biologists, genealogists, and anthropologists) a useful tool for studying human migration patterns, evolution, paternally linked relationships and identification. It has also been used to help locate the geographical origin of all human beings.
Y-STR Comparative Analysis
The Y-chromosome is of particular interest to researchers because of its
variability found among different human populations. To characterize the
Y-chromosome the DNA is genotyped at 26 different locations.
GeneTree provides the DNA profile data along with a comparative analysis after
examining the DNA for 2, or more, male subjects (Surname Test).
GeneTree uses this service to measure the likelihood of paternally-linked
relationships. Furthermore, the data can also be used to research your own
Y-chromosome DNA profile (NOTE: There are a number of publications that will
assist you with researching your DNA profile and how it relates to DNA profiles
of published populations. Contact us if you are interested in receiving a list
of publications that will assist you with this research).
