However , some elements of DNA are transmissible unchanged by offspring . For instance , the Y chromosome is ancestral by sons from their fathers and the mitoch ondrial DNA or mtDNA is passed on from mother to small fry (genomics .energy .gov . These DNA comp adeptnts can and do mutate from magazine to condemnation turning into genic markers that can be passed on from one generation to the nextOver the passage of time , people who inhabit a particular geographic area will have these crude ancestral markers and when they migrate , they carry these markers with them . The Y chromosome and mtDNA are resembling to genetic family names which permits males to trace their paternal genealogy and for some(prenominal) males and females to square up their maternal(p) genealogy (Mitotyping Technologies .

The biogeographic ethnicity of a somebody can also be inferred from DNA analysis . The mtDNA is primarily used in establishing the habitation of origin of a person s ancestors as well as other information on genetic backgrounds as claimed by many DNA scrutiny laboratories (Mitotyping Technologies .
