DNA testing reveals racial groups
Breaking Technology by Burleson Consulting
Ever wondered if your family tradition about having an American
Indian ancestor was true? Are you really a direct descendent
of Ivan the Terrible, or was your grant-grandpa just senile?
Well, wonder no more. Several companies are now providing
tests that can trace your
ancestry. We have has the mitochondrial (mother to mother
to mother) and Y chromosome tests (father to father to father) for a
few years, but vendors are now going beyond the "tail" tests to
include probabilities of racial groups, based on empirical data and
the human genome.
The problems of Y and Mito tests
The problem with mitochondrial and Y chromosome tests are that
you only get
limited data, regardless on how far back you go. In only
ten generations (about 300 years) you have 2**10, or 1024 distinct
ancestors and you will have absolutely no information on 1022 of
your direct ancestors.
The Y and mtDNA represent only a fraction of the human
genome, and reading ancestry from Y and mtDNA haplotypes only
tells 1/23rd the story (since there are 23 chromosome pairs).
However, these two chromosomes are inherited from parents as
single non-recombining units of DNA.
Vendor DNA testing offerings
Here is a vendor (DNAPrint Genomics) who claim to offer to go
beyond the Y and mito tests to give you a more global idea about
your racial and genetic makeup, while other vendors offer
race-specific test such as the
GeneTree Native American blood tests.
