Genealogy and DNA
DNA and genealogy are two topics that are closely linked. Together, they provide an invaluable resource for those interested in researching their family history.
DNA, or deoxyribonucleic acid, is the genetic material found in all living things. DNA contains the instructions for the development and functioning of all organisms. It is made up of four chemical components known as nucleotides. Each nucleotide contains a specific sequence of genetic code, which is unique to each individual.
Genealogy is the study of family history. It involves researching one’s ancestry to uncover information about their ancestors. Genealogists often use records such as birth, death, marriage, and military records to trace their lineage.
DNA and genealogy have become increasingly intertwined in recent years. DNA testing has made it possible to identify and trace family lines with unprecedented accuracy. Through the use of DNA testing, genealogists can find new information about the origins of their family and its members. This information can be used to confirm or refute traditional genealogical records.
DNA testing can also be used to identify distant relatives and match them to existing family trees. This can be done through a process known as genetic genealogy. Genetic genealogy involves comparing DNA sequences of the tested individual with those in the database e.g. Ancestry.
