Abstract:

Identification of selection signatures have become an important tool in population genetics and gene mapping of economically important traits with the explosion of genomic data. Using proper statistical methods and understanding the potential statistical problems in identification of selection signature are of great significance to accurately locate the candidate genes affecting economically important traits and reveal the potential genetic mechanism of adaptive evolution of livestock and poultry. This paper reviews the concept, the category of testing statistics of selection signature, the influencing factors and the related statistical problems in identification of selection signatures. It is expected to provide a reference for further research on identification of selection signatures.

Key words: livestock, selection signatures, statistical problems
