::mtDNA is sometimes thought to be the least useful test but this is only because it is not properly understood. Some pundits have said it is a fraud or a scam because it excludes all your ancestors but one from each generation. Five generations back you have 32 ancestors, but mtDNA only provides a signature for one of those from each generation, or 5 people. This is not a weakness. It is a significant strength in that if provides focused and more easily researched information. Y-DNA <em>(see below)</em> also provides focused information.

::mtDNA provides you with a signature for your matrilineal line. It is difficult in that it mutates so slowly that a perfect match between two individuals can indicate a relationship somewhere within hundreds of years. Its difficult is compounded by the fact that a woman's surname typically changes with each generation and, in may cases, may even be unknown.

::It is typically the most expensive test and, like mtDNA, it receives criticism for not being inclusive of all one's ancestors. Anyone who says that clearly has not used DNA for research. Being able to focus on one individual from each generation is very powerful.
