Mitochondrial DNA or mtDNA is beneficial for anyone who is looking to learn about their cousins or ancestors. It works by studying the tiny mitochondrial strands within a cell. These mitochondrial strands do carry ancestral information and are not changed even after extended time. So if you are looking to find more about your maternal line cousin or ancestor, you should go with mtDNA. With it, you can also learn about your ethnicity, region or family group.
Autosomal is appropriate if you are looking to learn about your family and its origins. There are 23 pairs of chromosomes, and with the autosomal test, you can compare 22 of them. The chromosomes need to be compared between the male and female member of the family. The test is precise but does come with few limitations. It only detects up to third or fourth cousins.
Y-Chromosome is the best possible DNA test to know about your ancestors. Y-Chromosome preserves the best possible information compared and hence is a great test if you want to know about ancestors. It can also be used to prove a relationship to ancestor or relationship with another individual. However, Y-Chromosome is only present in males. So, if you are a woman, you may ask any male in your family to do the test.
