| Abstract: | FecB gene was detected in Gansu meat sheep new breed population by PCR-RFLP,attempting to improve its reproductive performance.The results showed that there were two kinds of genotype(B+,++) in this population,but BB genotype was not detected.The genotype frequency of B+ and ++ were 0.30 and 0.70,respectively.Obviously,++ was dominant genotype in this population.It revealed that FecB gene located in intercrossing population was significantly deviated from Hardy-Weinberg equilibrium(P<0.01) by χ2 test,but a generation of Gansu meat sheep new breed population was not deviate from the Hardy-Weinberg balance(P>0.05).These results indicated that FecB gene could not be the fecundity trait gene in Gansu meat sheep new breed population. |
