ISPUB - What's There In Our Genes? A Case For A More Inclusive And ...

We need better reviews, use of both qualitative and quantitative data as well as much more rigorous testing of newer and older models. Only then may we make full use of this large amount of data that has already been collected over the years. What we have described here, for now, presents part of the picture seen from the Indian subcontinent as an example. However, this situation is probably true of other parts of the world as well, perhaps even those areas where it has been assumed that the data is likely to be homogenous. Thus, even biological anthropologists need to add new sensitivities [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...]

However, Mr Pye believed the samples were contaminated and had it re-tested by a different lab in 2004, which managed to recover mitochondrial DNA, but not nuclear DNA. This meant either the nuclear DNA was too degraded to recover, or the DNA from the father was too different from that of a human to be detected. This year, the skull was tested by an ultra high-tech genetic lab, which was unable to match part of the nuclear DNA samples to any other samples in the enormous genetic database at the US National Institutes of Health.

Can DNA Tests Reveal Nationality? » Scienceline

The Borders Agency is primarily using two types of DNA tests: mitochondrial DNA tests, which examine the genetic information stored in a cellular structure called a mitochondrion, and what are called Y-line tests, which look at markers on the Y-chromosome passed from father to son. These tests have been widely used to examine people’s ancestral heritage. Since certain genetic variations are typical in certain areas, geneticists can use an individual’s DNA to estimate where their ancestors came from. But when this technique is used to look at someone’s nationality rather than the origin [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. Cat DNA convicts murderer A body was found in a grave on Prince Edward Island, Canada. Police investigators identified the body as belonging to Shirley [more...]

Mitochondrial Disease can be diagnosed with a new test.

The SOLiD NextGen sequencing platform developed by Life Technologies was used for testing because of its low error rate and high throughput. This rigorous sequencing of mitochondrial DNA by MitoDx can detect mixtures (heteroplasmy) of normal and mutant DNA even when the mutant or normal form is present at very low levels. This allows mitochondrial disease to be evaluated much more sensitively in an accessible tissue like blood or saliva. Richard Boles, MD, the Director of the Mitochondrial and Metabolic Disorders Clinic at Childrens Hospital Los Angeles says, “MitoDx has confirmed the [more...]

Mitochondrial Eve screws Adam

The Mitochondrial Eve thing refers to the most recent common ancestor for all extant humans and is possible because mitochondrial DNA is inherited unmixed from the female parent. It's good science and currently points to the most resent common female ancestor living about 200 000 years ago somewhere in Africa and can be used as a predictor for the various migration hypotheses, for instance it casts doubt on the popular "out of Africa" hypothesis. Now the bible says people originated when god created Adam and Eve, and they were therefore the first two people. After the debacle with the fruit [more...]

Dienekes' Anthropology Blog: mtDNA of Yemeni and Ethiopian Jews

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.

How Fingerprinting Helps In DNA Paternity Testing

This form of fingerprinting method is also known as DNA profiling. Using this technique, the individuals are identified on the basis of their unique DNA profiles. This DNA profiling is done by analyzing the VNTR sequences. It stands for variable number tandem repeats. This sequence is found to be different in individuals except in twins. As per the facts mentioned above, the DNA samples of the child will exhibit the similar VNTR loci as that of their parents. This fingerprinting helps in identifying that whether the known father of a child is genuinely his biological dad. In fact, it is [more...]

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...]

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...]
