Paired box 7 (Pax7
) gene, a member of the paired box gene family, plays a critical role in animal growth and muscle development, especially in cell proliferation and self-renewal. In our study, the 10 bp duplication indel was detected in the promoter region within bovine Pax7
gene as well as its association with growth traits. This indel was significantly associated with the body weight in Xianan cattle, the body height in Jinjiang cattle, and the hip width in Pi'nan cattle.
