Resumen: El objetivo central de este documento es determinar la estructura genética y las preferencias residenciales de las poblaciones que habitan la Moskitia hondureña, un área amplia de selva lluviosa tropical que comprende el departamento de Gracias a Dios, en la republica de Honduras. Para esto, se calcularon los parámetros corrientes de isonimia dentro y entre los poblados, así como los patrones de residencia utilizando ambos apellidos, a partir del listado de 22,961 electores de 54 localidades agrupadas en seis municipalidades. Se observaron valores altos de isonimia aleatoria y predominancia de patrilocalidad en la mayoría de las comunidades, lo que revela una población estructurada y patrilocal, compuesta principalmente por comunidades aisladas, con la excepción de la ciudad de Puerto Lempira, la cabecera departamental. El análisis de isonimia entre comunidades reveló las rutas migratorias históricas más probables y la relación entre localidades. Los hallazgos sugieren que el departamento de Gracias a Dios es una población estructurada compuesta mayoritariamente por comunidades con alta endogamia y deriva génica, lo que la hace adecuada para la realización de estudios sobre enfermedades de herencia mendeliana y enfermedades complejas. La cabecera departamental, Puerto Lempira, puede ser la única localidad experimentando un rápido proceso de urbanización.

Summary: The main objective of this paper is to assess the genetic structure and residence preferences of the populations that inhabit the Honduran Moskitia, a wide area of tropical rain forest that comprises the Department of Gracias a Dios, in the republic of Honduras. For this purpose, common isonymy parameters within and between parishes, as well as residence patterns using both surnames were calculated from a list of 22,961 electors at 54 localities, grouped in six municipalities. High random Isonymy values and predominance in patrilocality were observed in most of the communities, revealing a highly structured, patrilocal population composed mainly by relatively isolated communities, with the exception of Puerto Lempira, the capital city. Analysis of isonymy between communities revealed the most probable historical migration routes and relations among locations. The findings suggest that the Department of Gracias a Dios is a structured population composed mostly by communities with high endogamy and genetic drift, which makes it suitable for the performance of genetic studies on mendelian or complex diseases. The capital city of the department, Puerto Lempira, may be the only one experiencing a fast urbanization process.
Key words: Surnames, Isonymy, Genetics, Population, Miskito, Gracias a Dios, Honduras
