Columbus may have carried a Jewish specific shared female lineage (HV0b) and the Cohen Modal Haplotype (J1c3, J2a), typical Jewish male lineages. But the documentary stopped short of naming specific haplogroups to confirm his Jewish ancestry.
The original scientific research was based on the hypothesis that a majority of present-day Jewish Kohanim share a pattern of values for six
Y-STR markers, which researchers named the extended
Cohen Modal Haplotype (CMH).
[5] Subsequent research using twelve Y-STR markers indicated that nearly half of contemporary Jewish Kohanim shared Y-chromosomal
J1 M267 (specifically
haplogroup J-P58, also called J1c3), while other Kohanim share a different ancestry, such as
haplogroup J2a (J-M410).
[6] The latest studies using single nucleotide polymorphic markers have further narrowed the results down to a single sub-branch known as J1-B877 (also known as J1-Z18271).
