Genetic architecture and candidate genes detected for chicken internal organ weight with a 600 K single nucleotide polymorphism array

摘要

ObjectiveInternal organs indirectly affect economic performance and well-being of animals. Study of internal organs during later layer period will allow full utilization of layer hens. Hence, we conducted a genome-wide association study (GWAS) to identify potential quantitative trait loci or genes that potentially contribute to internal organ weight.
