Resumen
Our objective was to analyse the genetic diversity of pigs from Uganda and obtain a more general picture about the ancestry of East African swine. Median-joining network analysis of D-loop sequences from 81 swine from Uganda and others with diverse origins allowed us to identify Western, Indian and Far Eastern genetic signatures in the East African pigs. This result agrees well with the high frequency of zebuine alleles in cattle from East Africa. The genotyping of five Ugandan pigs with the Porcine SNP60 Beadchip agreed well with an Asian/Western mixed ancestry, while sequencing of the Y-chromosome UTY locus in 18 Ugandan boars revealed the segregation of a single HY1 lineage that has a a cosmopolitan distribution. Our data demonstrate that pigs from East Africa have been targeted by multiple introgression events from other Western and Asian populations.
