Comparative analysis of mitochondrial deoxyribonucleic acid (adnmt) of individuals from Chiapas and Nicaragua. Evidence of their genetic relationship

Abstract

he original inhabitants of Mesoamerica developed great civilizations such as the Maya, Zapotec, Teotihuacan, and Aztec. One of these groups are the chiapanecas, who belong to the large group of the otomangues, who lived and still live from North Central Mexico to the coast of Chiapas, and along the Pacific coast from Nicaragua to the Nicoya Peninsula in Costa Rica.

We propose to study the mitochondrial DNA of Otomanguean groups and in particular one of them, the chiapanecas, who occupied the area between the center of Mexico to the San Juan River and the Nicoya Peninsula in Central America. This article is the result of a first exploration of genetic analysis based on the use of deoxyribonucleic acid mitochondrial (mtDNA) of current inhabitants of the city of Chiapa de Corzo (10 people, equivalent to 20 % of the sample), individuals originating in Nicaragua (21 samples, equivalent to 43 % of the total), as well as a set of 18 samples from people of different ori-gin, equivalent to 37 % of the sample, as a control group. The results suggest a genetic relationship between the inhabitants of Chiapa de Corzo with the Masaya from Nicaragua
