Genetic variation of high-altitude Ecuadorian population using autosomal STR markers

Abstract:

Fifteen autosomal STRs were analyze in order to elucidate the differences between low and high land Ecuadorian population. Seven Ecuadorian geographic areas (Tisaleo-Mocha, Cañar, Quito, Rocafuerte, Santa Rosa, Guayaquil and Lago Agrio) from different altitude were selected for the study. After the analysis, little genetic distances were observed between all cities, the more distant cities (FST = 0.02354) were Rocafuerte at an elevation of 17 m.a.s.l. and Quito at 2850 m.a.s.l. and the similar cities (FST = 0.00033) were Rocafuerte (17 m.a.s.l.) and Santa Rosa (10 m.a.s.l). In conclusion, there is not a great genetic distance in the 15 STRs reported in high and low land Ecuadorian population, therefore previously reported frequencies could been used in identification and paternity cases under analysis.
