Genomic selection estimates different chromosome fragments or single marker effect values through a large number of genetic markers in the whole genome and then accumulate the fragments or marker-effect values within the whole genome of an individual to obtain genomic estimated breeding value (GEBV). The reliability of GEBV depends on the size of the reference population, the effective number of chromosome fragments, and the methods used to predict marker effects. Therefore, extensive research is devoted to developing statistical models to predict marker effects.
