How is BGA analysis different from mtDNA and Y-chromosomal ancestry analysis?
• There are several commercially available tests of mtDNA(female contribution) and Y-chromosomal(male contribution) markers, which have been promoted as a means of learning one’s ancestral origins. Although these tests could provide information regarding the provenance of some of a person’s ancestors, they are very limited. For example, one generation ago a person has two ancestors, one mother and one father; five generations ago, a person has 32 ancestors; while 10 generations ago, a person has 1024 ancestors. Ten generations is roughly 250 years and within the time frame of genealogical interest, especially when we are considering the settlement of North America, because they only look at two (2) chromosomes. Y-chromosomal analysis and mtDNA analysis each could only provide information on a very small proportion of a person’s ancestors. Our test relies on sequences throughout your genome, so we can say more about a greater number of your ancestors.
