Modal haplotype

 ( Genetic Genealogy ) 

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 Kohen tradition). However, a specific modal haplotype may be determined for any genealogical DNA test-based surname project or other test group.

• 1-SNP " J2a Cohen Modal Haplotype" (J2a-CMH) All Y-DNA testers as of December 2025--with minor, explainable exceptions--who have the J-FGC4992 single nucleotide polymorphism (SNP) are of Jewish paternal heritage with an oral tradition of descent from the ancient Israelite priesthood. The genetics indicate that the time of the common ancestor for the 400+ known testers worldwide is roughly 500 to 900 BCE, consistent with that oral tradition.
