摘要: Polymorphism in Estrogen Receptor alpha (ESR alpha), Prolactin Receptor (PRLR), Luteinizing Hormone beta (LH beta) and the Ryanodine Receptor I (RYRI) genes, which play important roles in litter size of pigs, were analysed in four pig populations (Min, Landrace, York-shine, Duroc) using PCR-SSCP. There was one SNP in ESR alpha (Arg/His(488)), two SNPs in PRLR (one silent mutation and Val/Ala(555)) and two silent mutations each in LH beta and RYRI. PRLR was highly polymorphic locus (0.59 >= PIC >= 0.46), LH beta and RYRI were moderately polymorphic loci (0.36 >= PIC >= 0.15) and ESR beta was very low polymorphic locus (0.07 >= PIC >= 0.00).
