Assessing Sus scrofa diversity among continental United States, and Pacific islands populations using molecular markers from a gene banks collection.

ABSTRACT: Human migration and trade facilitated domesticated livestock movement, gene flow and development of diverse populations upon which agriculture is based. In addition, varying USA ecological conditions has led to a diverse set of livestock populations to utilize. Quantifying genetic diversity of these populations is incomplete. This paper quantifies genetic diversity captured by the National Animal Germplasm Program and explores genetic structure and differences among 19 pig populations (feral populations from Pacific islands, continental US, and Chinese breeds) using 70,231 SNP from 500 animal samples. Among continental US breeds F_is was consistently low suggesting genetic variability is sufficiently available for breeders to use. A unique population structure using principal com
