[A new polymorphic site of ESR gene in pigs].
ESR (Estrogen Receptor) gene has been determined to be one of the major genes affecting phenotype of litter size without any genetic negative correlation to growth and carcass trait. Recent studies mainly focused on the PvuII enzyme site found by Rothschild in 1996. An optimized standard PCR-SSCP protocol was employed to detect the exon 7 of ESR gene. The results showed that there were a new mutation site and three genotypes, which may be used as a new DNA marker site to further research.
