## Abstract
In order to investigate the genetic diversity, differentiation, gene flows, and propagation routes of Island Southeast Asian (ISEA) goats, we genotyped 50K genome-wide SNPs in 57 Philippine and 30 Indonesian Katjang goats. Correlations of the distance from the domestication center and the genetic diversities of 21 Asian populations were significantly negative. A relatively high diversity of the Philippine population (He = 0.363) against the distance from the domestication center suggests a history of admixture, notably without large effects on their Katjang phenotype. This was confirmed by supervised PCA (Principal Component Analysis), f3 coancestry and f4 admixture analyses, Treemix-inferred migrations and model-based clustering (Admixture program). The inferred differential admixture of ISEA goats agreed with previously reported fixation of mtDNA haplogroup B in Indonesia, but not in the Philippines, and with high frequencies of African or European Y-chromosomal haplogroups that were not observed in Mainland Southeast Asia. We propose that admixture of cosmopolitan European and African goats into ISEA was mediated by a unique feature of the domestic goat, the maritime transport of goats during the colonial period as a source of provisions. This was followed by more recent imports of popular breeds such as Boer, and other cosmopolitan breeds.
