Modal haplotype
Encyclopedia
A modal haplotype is an ancestral haplotype
derived from the DNA test
results of a specific group of people, using genetic genealogy
.
The two most commonly discussed modal haplotypes are the Atlantic Modal Haplotype
(the most common haplotype in parts of Europe, associated with Haplogroup R1b
) and the Cohen Modal Haplotype (the haplotype associated with the Jewish Cohanim
tradition). However, a specific modal haplotype may be determined for any genealogical DNA test

Genealogical DNA test
A genealogical DNA test examines the nucleotides at specific locations on a person's DNA for genetic genealogy purposes. The test results are not meant to have any informative medical value and do not determine specific genetic diseases or disorders ; they are intended only to give genealogical...

Atlantic Modal Haplotype
In human genetics, the Atlantic Modal Haplotype or haplotype 15 is a Y chromosome haplotype of Y-STR microsatellite variations, associated with the Haplogroup R1b. It was discovered prior to many of the SNPs now used to identify subclades of R1b and references to it can be found in some of the...

Haplogroup R1b (Y-DNA)
The point of origin of R1b is thought to lie in Eurasia, most likely in Western Asia. T. Karafet et al. estimated the age of R1, the parent of R1b, as 18,500 years before present....

Surname project
A surname DNA project is a genetic genealogy project which uses genealogical DNA tests to trace male lineage.Because surnames are passed down from father to son in many cultures, and Y-chromosomes are passed from father to son with a predictable rate of mutation, people with the same surname can...
