Genealogical DNA Tests
Y-Chromosome DNA Tests
Y-DNA37 - 37 Marker Test: tests the Y chromosome for genetic matches between males. Results are placed in FTDNA's Y-DNA database and when 2 people show the same identical or near identical results, they will inform both parties if you have both signed the FTDNA Release Form. A perfect match of 37 markers means a lesser number of generations before a Most Common Recent Ancestor (MRCA) can be determined. The customer receives a Certificate & report generally describing Y-DNA sequencing and the meaning of probability between matches.
OTHER STR TESTS: Y-DNA 67, Y111, BigY700
How many markers should I test?: The question asked the most often by people considering the Y-DNA test is ‘How many markers are enough?’
The place to start is to define the term ‘marker.’ A marker is a location on the Y chromosome that may be tested for Genetic Genealogy. These locations, or markers, have names, such as DYS #19 or DYS #385a or DYS #439. When a marker is tested, the result is reduced to a number, which represents the number of repeated patterns of the DNA protein sequence at a specific location on the Y chromosome.
The Lab we use, FamilyTreeDNA, offers 37+ marker Y-DNA tests. The difference is that the more markers tested for results, the further the reduction in the time frame to the Most Recent Common Ancestor, or MRCA. For all tests, the number of markers that match can determine whether you and another participant share a common ancestor and how many generations ago that common ancestor might have lived.
