One hundred and twelve pigs from Wannan Black population were used for detecting the polymorphism of CETP gene by PCR-SSCP method. The results show as follows.(1) C>T mutation(C795T) occurred in 795 base position of intron 1;(2) Three genotypes(CC, CT and TT) were found in C795T site, genotypic frequency of CC, CT and TT was 0.625 0, 0.303 6 and 0.071 4, respectively, gene frequency of C and T was 0.776 8and 0.223 2, respectively;(3) The polymorphism information content(PIC) was 0.286 6 in Wannan Black popu...
