The calculation of the paternal haplogroup is based on the genetic information contained in the Y chromosome. This chromosome is exclusive to males and is transmitted only from fathers to sons, allowing for a detailed tracking of paternal genetic history over generations. To determine the paternal haplogroup, specific genetic markers on the Y chromosome are analyzed, and the results are calculated using an algorithm that compares these markers with different paternal haplogroup databases. The extracted genetic information undergoes rigorous quality controls to ensure accurate results.
On the other hand, the calculation of the maternal haplogroup is performed using the genetic information contained in the mitochondrial DNA, which is inherited only from the mother. Mitochondrial DNA is present in the mitochondria of all cells and contains a circular chromosome that has accumulated mutations over generations. As with the paternal haplogroup, specific genetic markers of the mitochondrial DNA are analyzed and compared with maternal haplogroup databases. The calculation is performed using an algorithm that searches for genetic similarities and also undergoes quality controls to guarantee the accuracy of the results.
Both calculations provide detailed information about each user's genetic lineages and allow for the tracing of the historical journeys of their ancestors through the paternal and maternal lines.
