The G allele at the c.-312A > G SNP in the EDG1 gene associated with high marbling in Japanese Black cattle is at a low frequency in breeds not selected for marbling

摘要

Our previous study showed that a single nucleotide polymorphism (SNP), c.-312A>G, in the 5' untranslated region of the endothelial differentiation sphingolipid G-protein-coupled receptor 1 gene is associated with marbling in Japanese Black beef cattle, with the G allele resulting in high levels of marbling. There has been a strong selection for high marbling in the Japanese Black breed, but not in other breeds such as Japanese Brown, Japanese Short Horn, Holstein and Brown Swiss, over the past 50 years
