When selecting a test-taker, it is crucial to understand the inheritance pattern of mitochondrial DNA. Without traditional genealogical evidence to provide additional clues, mtDNA results can be difficult to incorporate into your research. With mtDNA results in hand, you can determine which of your autosomal matches are on the correct matrilineal line, and start to locate ancestors within a more recent genealogical timeframe.ДЄdditionally, you can collaborate with your autosomal/mtDNA cousin matches to build a shared family tree and try to determine a common maternal ancestor.Д«ut remember, in cultures where women changed their names at marriage and were more difficult to locate in records, having a detailed family tree for those female ancestors is essential.

This is a great opportunity to utilize both mtDNA and autosomal DNA testing results to narrow down the pool of potential cousin matches. However, keep in mind that the unchanging nature of mtDNA also presents a challenge when attempting to locate a shared ancestor within a particular genealogical timeframe, as all descendants on a maternal line will share the same, nearly identical mtDNA.ДЄ cousin match can indicate evidence of a shared maternal ancestor- but it cannot identify which woman in that shared ancestral line is the common ancestor.ДЄn mtDNA test can reveal that two people are maternally related, but cannot discern their relationship, so those with matching mtDNA may be mother and daughter, sisters, aunt and niece, or very distant cousins. There are existing mtDNA haplogroups, similar to Y-DNA haplogroups, which can help trace ancestral origins to a particular branch of the mitochondrial genetic family tree. Mitochondrial DNA also provides clues to ethnic and geographical origins by virtue of its unchanging nature over hundreds of years.ДЇor example, mtDNA may reveal if a maternal line has Native American, European, or African roots. When reviewing mtDNA cousin matches, a significant mismatch can rule out a relationship on that matrilineal line.ДЄdoptees may benefit from completing an mtDNA test, as the results can point them towards their biological motherвЂ™s family. This allows a researcher to use mtDNA results to trace a matrilineal line from mother, grandmother, great-grandmother, and so on. There is very little recombination or changing, of mtDNA as it passes down through the generations.

Mitochondrial DNA testing offers several important benefits to genealogy researchers. This is different than Y-DNA- which is exclusive to males and passed down from their fathers- and means that both women AND men can complete an mtDNA test. Therefore, both men and women carry their motherвЂ™s mtDNA, but only women will pass that mtDNA down to the next generation. Mitochondrial DNA is actually circular in shape, made of over 16,500 pairs of molecules called nucleotides, which help produce energy for each cell.ДЄ child will inherit mtDNA only from their mother, as mtDNA is passed down through a motherвЂ™s egg. This differentiates mtDNA from autosomal DNA, Y-DNA, and X-DNA, whose genetic data is located in the 23 pairs of chromosomes residing within the cellsвЂ™ nucleus.

Mitochondrial DNA is found outside the nucleus of each of your cells.ДЄlmost every cell in your body contains hundreds to thousands of copies of the mtDNA molecule. LetвЂ™s take a closer look at mtDNA and learn more about its unique possibilities! What is Mitochondrial DNA? It can aid adoptees looking for clues to their maternal family and can be combined with autosomal DNA test results to narrow down potential cousin matches and shared ancestors. Test results can help determine a common maternal ancestor, narrow your research focus, and provide insight into the ancient origins of maternal family lines. Mitochondrial DNA (mtDNA) can greatly benefit your DNA research, once you understand its potential applications. MtDNA is the mother genealogical DNA testing!
