|Logically, haplotypes (based on STR [short tandem repeat] testing) should correlate with haplogroups (based on SNP [single nucleotide polymorphism] testing), and they do. The correlation between haplotypes and haplogroups allows one to deduce the haplogroup from the haplotype, without the added expense of SNP testing. In the results tables, haplogroup designations without a corresponding SNP test are deductions based on the haplotype. For common haplotypes, the haplogroup deductions are usually correct; for questionable haplotypes, the deductions can be wrong. In these cases, FTDNA, as part of its "Haplogroup Assurance" policy, will conduct a "backbone" SNP test, free of charge, to securely determine the basic haplogroup.
The "modal" haplotypes for the haplogroup subclades given in the tables are just that (i.e., the most common pattern for the subclade); there are variations from the modal pattern, and variations at non-defining markers do not necessarily rule out membership in the subclade.
|SNP is treated, both in speech and in writing, as a word,
"snip," not spelled out "S-N-P." Hg is an abbreviation for Haplogroup.
NPE is the acronym for "Non-Paternal Event," meaning a hidden adoption
or illicit paternity in an individual's ancestry.
