This is bullcrap; repeatedly trying to sell your product on this forum.
Like most scams, this plays into people's propensity for greed. The
pittance coming from the federal govt is not even enough to touch the
intensely critical social problems on Amerika's reservations, and you're all
about getting people to pay over 200 bucks to find some shred of blood
quantum in the futile hope they can tap into some "free" govt money.
The folks on here are overwhelmingly lily white, regardless of what they'd
like others to believe. Yeah, I know, everybody's got a Cherokee princess
ancestor, or some chief back then (they're never just common folks!), and so
they "deserve" some of the booty. Claptrap!
To everyone else: do your homework before buying into this farce. Paying
this fool will not buy you a ticket into commodity wealth heaven.

Tracing Your Ancestry: Computer Program Accurately Analyzes Anonymous
DNA Samples
Science Daily - A group of computer scientists, mathematicians, and
biologists from around the world have developed a computer algorithm
that can help trace the genetic ancestry of thousands of individuals
in minutes, without any prior knowledge of their background.
Unlike previous computer programs of its kind that require prior
knowledge of an individual's ancestry and background, this new
algorithm looks for specific DNA markers known as single nucleotide
polymorphisms, or SNPs (pronounced snips), and needs nothing more than
a DNA sample in the form of a simple cheek swab. The researchers used
genetic data from previous studies to perform and confirm their
research, including the new HapMap database, which is working to
uncover and map variations in the human genome.
"Now that we have found that the program works well, we hope to
implement it on a much larger scale, using hundreds of thousands of
SNPs and thousands of individuals," said Petros Drineas, the senior
author of the study and assistant professor of computer science at
Rensselaer Polytechnic Institute. "The program will be a valuable tool
for understanding our genetic ancestry and targeting drugs and other
medical treatments because it might be possible that these can affect
people of different ancestry in very different ways."
Understanding our unique genetic makeup is a crucial step to
unraveling the genetic basis for complex diseases, according to the
paper. Although the human genome is 99 percent the same from human to
human, it is that 1 percent that can have a major impact on our
response to diseases, viruses, medications, and toxins. If researchers
can uncover the minute genetic details that set each of us apart,
biomedical research and treatments can be better customized for each
individual, Drineas said.
This program will help people understand their unique backgrounds and
aid historians and anthropologists in their study of where different
populations originated and how humans became such a hugely diverse,
global society.
Their program was more than 99 percent accurate and correctly
identified the ancestry of hundreds of individuals. This included
people from genetically similar populations (such as Chinese and
Japanese) and complex genetic populations like Puerto Ricans who can
come from a variety of backgrounds including Native American,
European, and African.
"When we compared our findings to the existing datasets, only one
individual was incorrectly identified and his background was almost
equally close between Chinese and Japanese," Drineas said.
In addition to Drineas, the algorithm was developed by scientists from
California, Puerto Rico, and Greece. The researchers involved include
lead author Peristera Paschou from the Democritus University of Thrace
in Greece; Elad Ziv, Esteban G. Burchard, and Shweta Choudhry from the
University of California, San Francisco; William Rodriguez-Cintron
from the University of Puerto Rico School of Medicine in San Juan; and
Michael W. Mahoney from Yahoo! Research in California.
The team's findings will be published in the September 2007 edition of
the journal PLoS Genetics.
Drineas' research was funded by his National Science Foundation Career
award.
