Mitochondrial DNA Analysis at the FBI Laboratory
In this diagram, females are represented by circles and males by squares. All individuals shown in blue should have the same mitochondrial DNA sequence because they are from the same maternal lineage. Thus, all three children of the first-generation parents have the same mtDNA, but only the children of the second-generation females share the same mtDNA sequences.
