2.The results showed that three genes such as HbB at Hb locus, TfC at Tf locus, Es- at Es locus diplayed certain correlation to the prolific trait of Small-tail Han sheep. Possibility of Ep to be used as the genetic marker should depend on further researches. The other four protein of AIb, Pr, AMY, LDH had no correlation to the prolific trait of Small-tail Han sheep, and couldn?t be used as the genetic marker.
