Abstract excerpt
BACKGROUND: Our group has previously identified a quantitative trait locus (QTL) affecting fat and protein percentages on bovine chromosome 6, and refined the QTL position to a 420-kb interval containing six genes. Studies performed in other cattle populations have proposed polymorphisms in two different genes (ABCG2 and OPN) as the underlying functional QTL nucleotide. Due to these conflicting results, we have...
