Genomic Selection–A Paradigm Shift in Animal Breeding
... A reference population of animals is scored for key production traits and genotyped using a commercial or custom SNP array. The genotypes are represented by the variable (x) with values 0,1,2 (homozygous, heterozygous, or alternate homozygous). A prediction equation is generated combining all the ma ...
