Have you ever wondered where you came from? I know I have. What paths did my ancestors take that led generations of their descendants to the exact place I am now? Where did their journey begin? My answer came through DNA. By researching the DNA of mitochondria and Y-chromosome I could trace my ancestral path and compare my father's and mother's migrations. I hypothesized the closest common ancestor (CCA) was in Africa. Materials/Methods: The National Geographic Genographic Project analyzed my mtDNA and Y-Chromosome. Six DNA kits were used. The mtDNAs investigated were for me, my father and my maternal grandfather. The Y-Chromosomes analyzed were from my father, my maternal grandfather and my mother's first cousin. The tissue samples were obtained from the subjects by using cheek swabs. The cheek lining was rubbed vigorously for 30 seconds, and the swabs were placed in test tubes containing DNA extraction buffers. Each kit had a number that was recorded and the tubes were sent to the National Genographic project. Data was gathered from the mtDNA and the Hypervarialble Region (HVR) of the mtDNA and compared to the Cambridge Reference Sequence (CRS) which is the standard mtDNA sequence used as a cross reference. Y-Chromosomes were analyzed by examining the twelve (12) separate loci where there are Short Tandem Repeats (STR) specific to the Y-Chromosome. STRs are where nucleotides repeat. The twelve loci looked at were: DYS393, DYS390, DYS19, DYS391, DYS385a, DYS385b, DYS426, DYS388, DYS439, DYS389-1, DYS392, and DYS389-2. Results: My maternal-grandfather's mtDNA, Haplogroup C, showed his female ancestors crossed the Bering Land-bridge 25,000 years ago. His mtDNA differed from the CRS in positions 16094C, 16223T, 16298C, 16325C, 16327T, and 16519C. His Y-chromosome also crossed the Bering land-bridge as part of Q1a3a (L53) Haplogroup. Hi Y-chromosome had 13 repeats of AGAT in DYS393, 24 repeats of TCTA TCTG in DYS19, 10 repeats of TCTA in DYS391, 14 repeats of GAAA in DYS385a and 18 in 385b, 12 repeats of GTT in DYS426, 12 repeats of ATT in DYS388, 13 repeats of AGAT in DYS439, 13 repeats in DYS389-1 and 17 repeats in DYS389-2 of TCTG and TCTA, and 13 repeats of TAT in DYS392. My mtDNA came from Germany with mutations, at loci: 16129A, 16172C, 16223T, 16311C, 16391A, and 16519C. My father's mtDNA is indigenous to America with mutations 16182C, 16183C, 16189C, 16217C, 16319A, 16519C. My father's mother's first-cousin's Y-chromosome results require further analysis. Conclusion: My mtDNA shows ancestry in Northern Europe. I have Mexican indigenous heritage through my Father's DNA. My Mexican-maternal-grandfather's Y-chromosome is the most predominant in the Americas. Summary: Three of the four lines for which I have results crossed the Bearing Land-bridge using three separate paths with their CCA in Africa. Interestingly my Mother's European line is more closely related to one of my indigenous lines, having split off from them in the Middle East.
