DNA parentage testing when the alleged parent is deceased – DNA Tests

These types of samples will require mtDNA testing techniques, as opposed to standard STR DNA, but can be useful in determining parentage. Since, often times, success can not be guaranteed with samples of the deceased, it is recommended that one consult with a DNA testing laboratory or expert to be advised of the best option for your specific situation. In some cases, it may be helpful to rely on samples from the alleged parent’s family members, which can sometimes indirectly establish parentage.

Eastman's Online Genealogy Newsletter: GeneTree is Now Out of Beta

A new Y-DNA genetic test enables individuals to research paternal line connections of a male relative, and complements GeneTree’s existing maternal line mtDNA test. Y-DNA results show ancestry and connections to DNA cousins within the past few hundred years.The opportunity to find and connect with “lost” or unknown extended family members through the world’s most extensive correlated genetic genealogy database is a compelling GeneTree feature. “My 82-year-old mother was almost in tears when I told her we had found a branch of our family that we had lost touch with long ago,” said [more...]

Family Tree DNA: What's happening in Houston?

Tracing the the Tribe just received the latest update from Family Tree DNA on what's been happening in Houston following Hurricane Ike and some issues impacting the company. In general, things are improving. According to president Bennett Greenspan and vice president of operations and marketing Max Blankfeld: a) The 5th Annual Conference on Genetic Genealogy will be postponed until February or March 2009, as the Sheraton Hotel has just informed us that they will not be in an appropriate condition to host our conference. The positive aspect of this postponement is that we will try our best to [more...]

Week of Winners Giveaway #6: GeneTree

What do you get when you combine mouth wash, genealogy, and science together in one package? The GeneTree DNA Test Kit* Are you saying, “Huh?” right about now? Well stick with me. When the folks at GeneTree approached me with this giveaway, my response was about the same. I mean, let’s face it–my experience with DNA would be limited to an evening with CSI Miami and Horatio Caine…hmmm…not a bad thought, but not where we’re headed. With the use of a simple mouthwash solution GeneTree will help you discover branches of your ancestry that you may never have know existed. GeneTree [more...]

Relationship DNA tests: X chromosome Test

Siblings, either male or female, wishing to establish whether they share the same mother (perhaps adopted children) would do a DNA maternity test or even more accurate an MtDNA test (mitochondrial DNA test). Relationship testing, as in the example of 2 females doing an X chromosome test to see if they share the same dad, will never be as accurate as a paternity test. The X chromosome test will show the probability of relationship between two females. No related [more...]

Dienekes' Anthropology Blog: DNA tests for asylum seekers

ScienceInsider has some reactions to plans from the UK Border Agency to use DNA tests to verify claims of asylum seekers that they do in fact come from the countries they claim (e.g., Somalia), rather than other ones which do not face the same geopolitical turmoil. This is a real problem for European countries, as many illegal immigrants without documents claim to be from war-zones. I am completely in agreement with the use of DNA tests to substantiate asylum seekers' claims, with the caveat that the followed protocols should be transparent to the scientific community, so that they can be [more...]

Book Review: Trace Your Roots With DNA

Trace Your Roots With DNA by Megan Smolenyak Smolenyak is a nice book for an overview of the field of genetic genealogy testing. It goes into detail describing the process of DNA testing and discusses what you can expect to learn from Y-DNA and mtDNA testing. Beyond that, Megan has a nice section on starting a group project and has information about where you can locate others in your same haplogroup or surname. Lots of good information here. My Opinion: Here's another good overview book that is successful at reducing the sci-cho babble to genealogy-speak. It's a book genealogists will be [more...]

Tribal DNA Test How Different American Indian Tribes Have ...

Generations of American families in the United States sometimes believe that they have Native American blood in their genes. If traditional research methods fail to produce any information, a DNA test may be just the thing you should try.Here are some things you should know about DNA testing and how it may determine which American Indian tribe you belong to:1. A DNA test can determine two of an individual’s many lineages.One way to determine a lineage is the mtDNA or the mitochondrial DNA test, which traces the genetic lineage along the maternal line. The Y chromosome DNA test, on the other [more...]

History Channel indicates first Native Americans were European

Scientists have recently discovered that "prior" to Asians crossing the Bering Strait about 10,000 B.C. to 15,000 B.C. (bringing us today what DNA testing companies consider "Native American") about 20,000 B.C. to 25,000 B.C. there was a migration out of Southwestern Europe of peoples of European origin who made their way along the Ice Sheets in boats in the Atlantic Ocean who settled in the Eastern United States. The oldest spearpoints ever found in North American have SW European origins not Asian origins - therefore, once again - if your family was from the eastern U.S. or eastern Canada [more...]

Tracing Birth Parents by Testing Your DNA

The tests can even distinguish a half sibling from a full sibling. If you followed my advice and used both Family Finder and Relative Finder, you can test the suspected relative with whichever test costs less. Both should do a good job of confirming a close relationship. NOTE: Do not count on a Y-DNA test for close relationship testing. While Y-DNA matches definitely share a common paternal ancestor, the test can only tie you to a family, not to any one person. Mitochondrial DNA? Both men and women can also take a mitochondrial (mtDNA) test that follows the maternal line. But learning [more...]

How to Maximize Free DNA Testing

DNA testing has not been limited to the study of the human gene, but has also included that of our beloved canines. DNA testing centers for dogs are open to identify the breeds and ancestry of our pets. Free DNA testing also shoots from legal cases with proceedings done underway. DNA testing for these circumstances can include not only the victim and possible suspects but also other individuals present at the crime scene. Some legal reasons that require DNA testing are for alimony or patrimony reasons. In these cases, the genetic markers are looked into to determine, for example, the [more...]

The way I see it, only a large-scale study of all global Jewish populations may uncover verified ancient Jewish lineages for both Y-chromosomes and mtDNA. The recent studies on Jews have uncovered several genetic sub-clusters of Jews, and only lineages that occur in 2 or more of these clusters, and preferably geographically separated ones have a strong claim of representing original Jewish lineages. There is a limit on what can be uncovered about the past from the study of living populations.

mtDNA haplogroup H occurs very frequently in Caucasoids. This means that even if additional HVRI/HVRII information is known, there is still a high probability that two H samples with the same mutations in the hypervariable regions may not in fact be closely related. Testing for the sub-haplogroups of H is a way in which additional information about haplogroup H samples may be obtained. The authors find that this is quite useful and that the distribution of H sub-haplogroups is significantly correlated with geography. From the article: Most of the European populations sampled display an [more...]

Mitochondrial DNA Genealogy

The mitochondrial DNA genealogy is the study of a person’s mother’s family line of maternal ancestors. This DNA is passed down from mother to each of her children exactly as she has it, with no mutations, except in the very rare instances. Because of the traditions in our society of the wife taking her husband’s last name, a surname genealogy trace of the female line of the family tree is more difficult. On the flip side, since this DNA strand is more stable than the Y DNA, more conclusive results can be determined for the testing of it. The mt-DNA is sometimes referred to as the Full [more...]

Cat DNA Can Aid in Criminal Investigations | easyDNA Blog

If you have ever inquired about a hair DNA test or know some of the basics of DNA you may know that DNA is found throughout nucleated cells in the body. Since hairs are simply made up of protein then we know that there is no nuclear DNA in hair. The same applies for cats- there is no nuclear DNA in cat hair. However, cat hair and human hair contain what is known as MtDNA (mitochondrial DNA) and this, like nuclear DNA, is unique to each of us.

Ancestry DNA Testing

DNA research worldwide led to the discovery of genetic markers that are used to evaluate ancestry. These markers follow three types of inheritance pattern categories. These are autosomal DNA line, the paternal DNA line and maternal DNA line. The autosomal DNA line is made of all DNA in the cells excluding the X – chromosome, Y – chromosome and mtDNA. A person inherits half of autosomal DNA from the biological mother and the other half from the biological father. The Y chromosome markers are paternally related and passed from a father to his son. They are used to trace a person’s [more...]
