A Matrilineal Study on the Origin and Genetic Relations of the Ecuadorian Pillareno Creole Pig Population through D-Loop Mitochondrial DNA Analysis.

ABSTRACT: Domestic pig breeds reached America on the second Columbus trip; from this date, Iberian pig genetic resources were disseminated throughout the continent, forming diverse creole breeds. These Ecuadorian Creole pigs are important for food production but have been genetically eroded since the introduction of transboundary breeds. In this study, we sought to characterize this erosion more thoroughly through mitochondrial DNA D-Loop analysis of Ecuadorian Pillareño Creole pigs from seven regions of Ecuador. To allow comparison, we also included in our analysis sequences from wild species, commercial lines, and domestic pigs, which were obtained from the NCBI GenBank database. Creole pigs' population showed overall moderate Hd values and low π values, and a negative value of Tajima's D was obse
