Haplogroups in green have been confirmed by SNP testing. Haplogroups in red have been predicted by Family Tree DNA based on unambiguous results in the individual's personal page. This has been placed on this GAP page for your ease and convenience. Please note that for any predicted results we see no reason for ordering a SNP test to confirm the Haplogroup. If a – is in the HAPLO field then we feel that the comparative results are not clear and unambiguous and if the kit holder wants to know their SNP with 100% confidence they may consider ordering a SNP confirmation test.
DYS 19 is also known as DYS 394.
It is obvious from our observation of 1000's of samples that some markers change or mutate at a faster rate than others. While that actual 'faster rate' has not yet been definitively calculated, not all markers should be treated the same for evaluation purposes.
The markers in red have shown a faster mutation rate then the average, and therefore these markers are very helpful at splitting lineages into sub sets, or branches, within your family tree.
Explained another way, if you match exactly on all of the markers except for one or a few of the markers we have determined mutate more quickly, then despite the mutation this mismatch only slightly decreases the probability of two people in your surname group who match 11/12 or even 23/25 of not sharing a recent common ancestor.
