Lending new life to the demise of Louis XVI, scientists performed a battery of DNA tests on dried blood inside a decorative gunpowder gourd that purportedly contained one such handkerchief. The results, described Oct. 12 in the journal Forensic Science International: Genetics, show the blood belongs to a blue-eyed male from that time period: a possible dead-ringer for the executed king. “The next step is find a descendant either of the king or his mother,” said Davide Pettener, a population geneticist at the University of Bologna in Italy who helped with the analysis. “Otherwise [more...]

DNA Testing, Vital for Genealogy?

Test should also explain that research in your family tree, whether is true or not. One kind of DNA test for genealogy that is available to the public is the mtDNA Test. mtDNA is a kind of DNA which is passed down by your mother to all her children and this does not get mixed with other DNAs. Therefore, it is an important determinant of good in front of your mother since his is the same mitochondrial DNA, which is also the same mitochondrial DNA from the mother, and is again the same thing his mother, and so on. Take a long time, for it can be changed so if two people are suitable for mtDNA, [more...]

Information About Non Paternity And Non Maternity

All the same, requirements for consent and counselling for DNA testing are unique from each country's laws and policies. DNA testing would be the most state-of-the-art and precise technique to figure out both non-paternity and non-maternity. In figuring out if the presumed parents are genuine biological ones or in determining actual biological mother or father-child bond, subjects undergo parental screening. This sort of practice uses the genetic fingerprinting (or DNA profiling), that is a approach to recognize identity by means of DNA profiles. A paternity test serves as an inherited proof [more...]

Dienekes' Anthropology Blog: Y-STR mega-paper (Ballantyne et al. 2010)

To rectify this, we analyzed a large number of 186 Y-STR markers in nearly 2000 DNA-confirmed father-son pairs, covering an overall number of 352,999 meiotic transfers. Following confirmation by DNA sequence analysis, the retrieved mutation data were modeled via a Bayesian approach, resulting in mutation rates from 3.78 × 10−4 (95% credible interval , 1.38 × 10−5 − 2.02 × 10−3) to 7.44 × 10−2 (95% CI, 6.51 × 10−2 − 9.09 × 10−2) per marker per generation.

Y Chromosome tinkering

The other women's mitochondrial lines died out when either they had only sons (who would not pass on the mitochondrial DNA) or no children at all, leaving only hers. Same for the Y chromosome Adam, an ancestor of all men alive today who lived 60,000 years ago. He was not the only man alive, but the other men's lines all ended across the 60,000 years when they either had only daughters (who do not have a Y chromosome) or no children at all. This was further sped up by Genghis Khan, a Mongolian ruler who had a lot of children, who in turn had many more children. He is the ancestor of 16 million [more...]

Mitochondrial "Eve" lived 50,000 years before Y-Chomosomal "Adam" but the theory is that every human today can trace their mitochondrial DNA through their mothers to this one female, and all males can trace their paternal lineage to this one male.

Genetic DNA Testing, The Use And Benefits

Due to recent advances in scientific knowledge and high technology, DNA genetic testing is now developed and commonly used by most people. DNA test is relatively used for paternity analysis of various genetic diseases during pregnancy and for forensic investigations. Paternity tests are used to determine who is the biological father of a child. Sometimes, when parents do not know about the paternity of a child, this can affect their relationships and peace of mind, governed by the father of DNA testing. It is important to know the paternity of the child’s legal aspects, such as birth [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. There is a limit on what can be uncovered about the past from the study of living populations.

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...]

Using Genetic Genealogy to Discover Royal Relatives - Genealogy ...

The DNA testing revealed that Mr. Holland is a long-lost relative of a ruling family in Cameroon, West Africa. In November, Mr. Holland will take his American family, including his 79 year old mother, to Cameroon, to visit with his African family. How exciting!This is one example of how genetic genealogy can be used. Genetic genealogy looks at a select number of DNA markers, (instead of examining the entire genome, or the information used for paternity tests). In general, there are two ways to go. The company offering services in genetic genealogy may look at the Y-chromosome, which is passed [more...]

Mutation Rate In Humans Gets Measured By Direct Sequencing

With better measurements of mutation rates, we could improve the calibration of the evolutionary clock, or test ways to reduce mutations, for example. Even with the latest DNA sequencing technology, the researchers had to design a special strategy to search for the vanishingly rare mutations. They used next-generation sequencing to establish the order of letters on the two Y chromosomes and then compared these to the Y chromosome reference sequence. Having identified 23 candidate SNPs – or single letter changes in the DNA – they amplified the regions containing these candidates and [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...]

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...]
