Association of Rs339939442 in the AHR Gene with Litter Size are Inconsistent among Chinese Indigenous Pigs and Western Commercial Pigs.

ABSTRACT: Eastern and Southern Chinese pigs have been imported to Western countries to improve economic traits including fertility in Western pig breeds by intensive selecting Chinese advantage genes. It was reported that the selected Asian-derived non-synonymous mutations including rs339939442 (G > T) in the aryl hydrocarbon receptor (AHR) gene could increase litter size in multiple European commercial lines. The objective of this study is to identify whether rs339939442 in the AHR gene is polymorphic and has an influence on the litter size in 10 pig populations including five Chinese indigenous breeds, one cultivated breed, one lean-type breed, two North American lean-type breeds, and one European lean-type breed. We found that rs339939442 had polymorphism in all 10 populations, whereas rs33993944
