Dna Testing As Biochemcial Geneology

a: Mitochondrial dna testing ~
b: maternal biochemcial geneolgy

What: As note just about every where, mammals, human beings can trace their maternal lineage by having their mitochondrial DNA sequenced. This DNA does not cross-over with male DNA and therefore its sequence shows much lower variability than nuclear DNA that has been recombined with paternal DNA. So a comparison of an individuals DNA to other's DNA can give a hint about how closely they may be related, on the mother's lineage.
