The Early Stages of the Genetic Genealogy Revolution

It’s always been my belief that personal genetics (inexpensive whole-genome analysis) will bring about some exciting changes in the field of genetic genealogy.One of the biggest areas of change will undoubtedly be in the area of autosomal genetic testing.(Remember that autosomal testing examines nuclear DNA, which is DNA other than mtDNA, Y-DNA, or X chromsomes).

A new study takes one of the first steps in the genetic genealogy revolution by examining SNP variations in four self-identified American populations – European, Latino/Hispanic, Asian, and African American (see reference below).“These population labels were used, despite the controversy surrounding the correspondence between notions of race and population structure inferred from explicit genetic data, because they are the labels used by NIH, FDA, and many, if not most, biomedical researchers.”The researchers sequenced the exons and flanking regions of 3,873 genes from 76 unrelated individuals.
