Haplogroup A3 is a branch on the maternal tree of human kind. Its age is between 2,200 and 11,300 years (Behar et al., 2012b).

Haplogroup A5a is an East Asian branch on the maternal tree of human kind. The woman who founded this line lived between 5,600 and 10,400 years ago (Behar et al 2012b).

Haplogroup A7 is a branch on the maternal tree of human kind. The woman who started this branch lived at some point between recent generations and 15,700 years ago (Behar et al., 2012b).

Insights into the origin of rare haplogroup C3* Y chromosomes in South America from high-density autosomal SNP genotyping

In summary, we can exclude recent migration and probably admixture 6 Kya as the source of the C3* Y chromosomes in Ecuador, and thus suggest that they represent a rare founding lineage lost by drift elsewhere.

16 Y chromosomal STR haplotypes in Japanese

A total of 1079 Japanese males were typed for the following 16 Y chromosomal short tandem repeat (Y-STR) markers: DYS456, DYS389I, DYS390, DYS389II, DYS458, DYS19, DYS385, DYS393, DYS391, DYS439, DYS635, DYS392, Y GATA H4, DYS437, DYS438 and DYS448 using an AmpFlSTR® Yfiler™ PCR Amplification kit (Applied Biosystems). A total of 950 haplotypes for the 16 Y-STR markers were detected and, of these, 886 haplotypes were unique.

Mitochondrial DNA Haplogroup D4a Is a Marker for Extreme Longevity in Japan

The conclusion is that the correlations are entirely due to population structure (phylogenetic tree). We find no signal for a functional mtDNA SNP correlated with longevity. The fact that the correlations are from the population structure suggests that hitch-hiking on autosomal events is a possible explanation for the observed correlations.
