Abstract excerpt

Genomic selection (GS) accelerates genetic improvement in poultry, but the high cost of high-density SNP arrays limits its large-scale application. Here, we developed and validated a cost-effective 10 K SNP array for chickens based on 55 K array data from 58,496 individuals across 16 commercial lines. The genome-wide panel comprises 10,000 SNPs using a multi-step strategy that integrated the fixation index (FST),...
