Single Nucleotide Polymorphism and Its Use in Chicken QTL Mapping
单核苷酸多态性及其在鸡QTL定位上的应用 Single Nucleotide Polymorphism and Its Use in Chicken QTL Mapping

Single nucleotide polymorphism (SNP) refers to the change of single nucleotide in DNA sequence.Because of its high density in genomes and easy in detection and analysis statistically,SNP can be used in genetic linkage map construction and QTL mapping.Here,the characters and detecting technology of SNP,as well as the status and foreground of the use of candidate gene SNP in chicken QTL mapping are introduced.
