Short summary
The expression and polymorphism of the BMPR1B gene associated with litter size in small-tail Han (STH) sheep were determined. We found that BMPR1B was mainly expressed in reproduction-related tissues and was more highly expressed in the hypothalamus of polytocous than in monotocous ewes in the follicular and luteal phases. A new molecular marker was found and was negatively correlated with litter size in STH sheep. These results can provide a reference for selective sheep breeding.
