A review of research progress of FecB gene in Chinese breeds of sheep.

Abstract excerpt

FecB gene is a major gene responsible for high prolificacy firstly identified in Booroola Merino sheep. Subsequently, many other aspects of the FecB including endocrinology, fetal and postnatal growth were studied. A forced PCR-RFLP method was performed to screen some Chinese breeds or strains of sheep to determine if FecB gene is responsible for their high prolificacies. The FecB gene was present in some Chinese...
