GeneSaver DNA Preservation Service

GeneSaver® DNA Preservation Service

Genealogy and Molecular Genetics

More and more genealogists are relying upon DNA studies to define family heritage. Samples preserved by GeneSaver are protected from contamination, tampering or atmospheric degradation and can be stored indefinitely without requiring refrigeration. Confidentiality is assured, because the family controls all uses of its stored DNA.

As both humans and animals tend to breed within limited geographical ranges, DNA fingerprinting has been useful in studying their migratory habits. DNA studies have linked animals born far apart, such as Alaskan and California bears. DNA similarities in isolated groups of humans in North and South America suggest previously unsuspected migratory patterns. Studies have found close correlations between genetic similarity and languages. As more findings are reported, we start to learn about the geographic origins of early man and his movements across continents, explaining the rise and fall of ancient civilizations.

DNA fingerprinting has traversed a rocky trail, largely because the ever-present hazard of contamination plays such a significant role in forensic specimens. Law-enforcement agencies have now become more aware of the value of DNA identification and are training their personnel in the proper handling of evidence. And DNA samples are becoming ever more important as means of ensnaring criminals in all levels of society. Recently, DNA studies have been used to prove or disprove paternity in cases involving inheritance of large estates.

DNA confirms the familial relationships of prominent families with their slaves, but it is a mistake to attribute such a relationship to one person, such as in the case of Thomas Jefferson, if other males in the family could have been responsible for the DNA blending that makes America such a fascinating field for the study of molecular genetics.
