Yes, that's true, but the mitochondrial DNA only has the genes encoding proteins involved in the mitochondrial metabolism, and not all of them even. So mitochondrial DNA is great for genetical studies on evolution, population biology, speciation etc., but the DNA itself does not do much about the individual characteristics and absolutely nothing about the genetical variability of the population, it actually includes some of the most conserved genes there are - those are genes that are least changed as time goes and are very similar even in very unrelated species.
