Genealogical DNA tests have become popular due to the ease of testing at home and their supplementing genealogical research. Genealogical DNA tests allow for an individual to determine with high accuracy whether he or she is related to another person within a certain time frame, or with certainty that he or she is not related. DNA tests are perceived as more scientific, conclusive and expeditious than searching the civil records. But, they are limited by restrictions on lines which may be studied. The civil records are always only as accurate as the individuals who provided or wrote the information.
The aforementioned Y-DNA testing results are normally stated as probabilities: For example, with the same surname a perfect 37/37 marker test match gives a 95% likelihood of the most recent common ancestor (MRCA) being within 8 generations, while a 111 of 111 marker match gives the same 95% likelihood of the MRCA being within only 5 generations back.
As presented above in mtDNA testing, if a perfect match is found, the mtDNA test results can be helpful. In some cases, research according to traditional genealogy methods encounters difficulties due to the lack of regularly recorded matrilineal surname information in many cultures.(see Matrilineal surname).

Famous quotes containing the word benefits:
“When your parents are in political life, you aren’t normal. Everybody talks about the benefits, but I don’t know what the benefits are.... But I’d rather have that kind of mother than an overweight housewife.”
—Katherine Berman Mariano (b. 1957)
“In America the young are always ready to give to those who are older than themselves the full benefits of their inexperience.”
—Oscar Wilde (1854–1900)
“Unfortunately, we cannot rely solely on employers seeing that it is in their self-interest to change the workplace. Since the benefits of family-friendly policies are long-term, they may not be immediately visible or quantifiable; companies tend to look for success in the bottom line. On a deeper level, we are asking those in power to change the rules by which they themselves succeeded and with which they identify.”
—Anne C. Weisberg (20th century)
