Resumen
Los avances tecnológicos de la genética han dado origen a la ciencia de la Genealogía Molecular, al brindarnos la
posibilidad de abordar el estudio de las genealogías desde una nueva perspectiva, examinando personas vivas a la
vez que se coteja la información documental de sus ancestros (Jobling 2001, Perego et al. 2005).
En nuestros días se han popularizado una serie de iniciativas para el estudio de las relaciones de parentesco entre
los humanos, tales como el Proyecto Genográfico (National Geographic Society 2008) o el de la Fundación Sorenson de Genealogía Molecular (SMGF 2008), y diversas compañías privadas, como la Family Tree DNA
(2004). Todas estas ofrecen servicios para el análisis del ADN mitocondrial (ADNmt) de hombres y mujeres, y del
cromosoma Y exclusivamente de los varones. Así, muchas personas deciden hacerse analizar sus marcadores
genéticos como una iniciativa personal, o participan en proyectos donde su información genética es incorporada en
grandes bases de datos públicos o privados, o adicionan voluntariamente sus resultados en tales bases
informatizadas, por ejemplo en la “Mitosearch” (Family Tree DNA 2004), con los objetivos de buscar parientes
biológicos y de adquirir conocimiento respecto a su origen remoto. Recordamos que el ADNmt tiene una herencia
materna estricta y una gran variabilidad que lo hacen útil para realizar estudios históricos y evolutivos (Stoneking
1993).

Thus, many people decide to have their markers analyzed genetic information as a personal initiative, or participate in projects where their genetic information is incorporated into large public or private databases, or voluntarily add their results to such databases computerized, for example in “Mitosearch” (Family Tree DNA 2004), with the objectives of searching for relatives biological and to acquire knowledge regarding their remote origin. We remember that mtDNA has an inheritance strict maternal and great variability that make it useful for carrying out historical and evolutionary studies (Stoneking 1993).
