The Consistencies of Y-Chromosomal and Autosomal Continental Ancestry Varying among Haplogroups

Evaluating Self-declared Ancestry of U.S. Americans with Autosomal, Y-chromosomal and Mitochondrial DNA

The current U.S. population represents an amalgam of individuals originating mainly from four continental regions (Africa, Europe, Asia and America). To study the genetic ancestry and compare with self-declared ancestry we have analyzed paternally, maternally and bi-parentally inherited DNA markers sensitive for indicating continental genetic ancestry in all four major U.S. American groups. We ...

Exploring the Y Chromosomal Ancestry of Modern Panamanians

Geologically, Panama belongs to the Central American land-bridge between North and South America crossed by Homo sapiens >14 ka ago. Archaeologically, it belongs to a wider Isthmo-Colombian Area. Today, seven indigenous ethnic groups account for 12.3% of Panama's population. Five speak Chibchan languages and are characterized by low genetic diversity and a high level of differentiation. In addi...

Y-chromosomal binary haplogroups in the Japanese population and their relationship to 16 Y-STR polymorphisms.

We investigated Y chromosomal binary and STR polymorphisms in 263 unrelated male individuals from the Japanese population and further examined the relationships between the two separate types of data. Using 47 biallelic markers we distinguished 20 haplogroups, four of which (D2b1/-022457, O3/-002611*, O3/-LINE1 del, and O3/-021354*) were newly defined in this study. Most haplogroups in the Japa...
