Every cell in our body contains hundreds to thousands of these tiny, football-shaped organelles.
Mitochondrial DNA (usually abbreviated as mt DNA) is passed to offspring only’ through the egg.
Thus, it is not a combination of male and female genes.
It is a haploid gene — meaning that it has only’ one dose of chromosomes. Diploid genes are two sets of combined chromosomes, the female set coming from the egg, the male chromosomes from the sperm.
This section adapted from Mound Builders: Edgar Cayce's Forgotten Record of Ancient America by Gregory L. DNA analysis on Native Americans began in the 1980s, but with rapid technological improvements. Several teams of genetics researchers at prominent American universities have been conducting numerous studies.
Although results from early studies showed the expected Siberian-Asia ancestry of the majority of modem Native American tribes, things took an At that point it was found that a small percentage of modem Native Americans have an unusual type of DNA then known to exist out’, in a few locations in Europe and the Middle East.
Subsequent research indicated that the European DNA was no the result of genetic mixing after Columbus.
In addition, the same DNA was later found in the hone of an ancient American burial confirming that people carrying this unique DNA had entered America in ancient times.
However, in July 200, this unique gene was also found in a small tribe living in the northern Gobi Desert area.
The DNA research initially seemed to promise solid proof of not only where the ancient Americans came from, but also when they came.
However as might be expected, ancient DNA research has become a highly contentious issue with several competing sides.
Most of’ the DNA research on Native American Indians has been done utilizing mitochondria.
