The Microsatellite Polymorphism Research on Porcine Chromosome 1 and the Construction of Its Genetic Map
猪1号染色体微卫星多态性研究及遗传连锁图谱的构建

As a molecular marker,microsatellite has many advantages such as high polymorphism and good conserva-tiveness in animal genetic research. The study chose 8 microsatellite markers that evenly distributed on chromosome 1 with a distance about 20 cM to build the genetic map of porcine chromosome 1. The results of our experiment are as follows:the number of alleles for 8 markers is 2 to 5,their gene frequency is from 0. 015 to 0. 75,the heterozygosi-ty is from 0. 39705 to 0. 67675 and the polymorphic information content is from 0. 32925 to 0. 59316. The map we built is basically in consistent with the result of USDA and can be used in searching quantitative traits loci in pigs.
