The chart below shows the interpretation of your relationship at each testing level (Y-DNA12, Y-DNA37, etc.) for relevant genetic distances. For example, if you and your match have both tested at the Y-DNA37 level and are a 36/37 match, this is a genetic distance of one. You are then considered tightly related. Y-DNA12. Y-DNA25. Y-DNA37. Y-DNA67.
Y-DNA Genetic Distance. When talking about two or more Y-chromosome STR (short tandem repeat) haplotypes, genetic distance is the total number of differences or mutations between two sets of results. In general, it is found by summing the differences between each STR marker. For example, kit B291 and B125 have allele values of 29 and 28 …
Y DNA Distance Charts Please note that Kits C4BMF, 3W275 & C4BMF were not tested through the same facility. They had 43 markers tested, but not all were the same as those tested at FTDna, so I can only provide comparisons for those markers which were duplicated.
12 Marker Genetic Distance Chart . The table below reflects the genetic distance between the participants results. A distance of 0 is an exact match, a distance of 1 is a single step mutation, etc.. The distance calculation was provide by the Family Tree DNA group administration page.
