Mitochondrial DNA is only a small portion of the DNA in a eukaryotic cell; most of the DNA can be found in the cell nucleus and, in plants, in the chloroplast. In humans, the 16,600 base pairs of mitochondrial DNA encode for only 37 genes.
Family Tree DNA offers the analysis of mitochondrial DNA, which is found in both men and women. mtDNA traces the matrilineal all-female line. Family Tree DNA offers testing of the HVR1 region, HVR2 region, and the Full Mitochondrial Sequence (FMS) which sequences the entire mitochondrial genome.
