Some rape cases result in the pregnancy of the victim and if the case is not reported to the police after the act with a subsequent gynaecological examination of the girl and the taking of a vaginal swab, there is no way of connecting the rape case with the perpetrator, except by parentage determination using DNA (deoxyribonucleic acid) analysis after abortion or induced delivery. In order

The internet offers a great range of possibilities to search for and find information from known and forgotten ancestors and family members. Filling the leaves of our family tree has become easier than ever before. However, the next breakthrough does not come from Google labs but from the scientific advances that have made it possible to perform personalized genetic testing and DNA sequencing

Reconstructing the genealogy of a common surname may seem a daunting task. In spite of this, the LEWIS Surname DNA Project has been established in 2003 to gather information from as many Lewis family groups as possible. Since then, the idea has become is one of the larger DNA surname projects, with almost 240 participants.The website dedicated to promote this project invites all interested

A Y-STR DNA test can be employed to confirm your relationship to relatives and paternal ancestors. This DNA test can be used too to obtain evidence in paternity cases where an alleged father is not present. It can be performed to see whether or not a child is a relative of the alleged father's brothers or other male. The genealogy DNA test represents the fact that the Y chromosome is inherited

Mitochondrial DNA is a very useful tool in forensic science. It has been used to identify the human remains and the perpetrators of a crime. It was also used to determine ancestry.In traditional DNA tests, the nuclear DNA is used. Nuclear DNA (nDNA) can be removed from all nucleated cells. However, there are cells that do not contain nuclear DNA. These cells are called non-nuclear DNA of cells.

Chromosome Y can only be found in men. It has the form and function distinctive because it involves sex-determination during embryonic development (A male contains a human X chromosome and one Y chromosome).Other than that, Y chromosome DNA contains paternal which is used in determining the father of descent (patrilineality), as it is passed from father to son. This is because most of the Y

The accuracy of DNA paternity testing is a question that many people asks when looking into having a DNA test done. Although no test can ever be 100% accurate, the importance of this relies on how confident you can be on the result, or how likely is that the paternity test results will resolve your paternity doubts.Two kinds of results are involved in a paternity test.
