Genome-wide association study provides insights into the genetic architecture of bone size and mass in chickens.

Abstract excerpt

Bone size is an important trait for chickens because of its association with osteoporosis in layers and meat production in broilers. Here, we employed high density genotyping platforms to detect candidate genes for bone traits. Estimates of the narrow heritabilities ranged from 0.37 ± 0.04 for shank length to 0.59 ± 0.04 for tibia length. The dominance heritability was 0.12 ± 0.04 for shank length. Using a linear...
