Genome‐wide association study of shank length and diameter at different developmental stages in chicken F2 resource population

4 monthes ago   |   By Animal Genetics

Abstract
In order to find SNPs and genes affecting shank traits, we performed a GWAS in a chicken F2 population of eight half‐sib families from five hatches derived from reciprocal crosses between an Arian fast‐growing line and an Urmia indigenous slow‐growing chicken. A total of 308 birds were genotyped using a 60K chicken SNP chip. Shank traits including shank length and diameter were measured weekly from birth to 12 weeks of age. A generalized linear model and a compressed mixed linear model were applied to achieve the significant regions. The value of the average genomic inflation...
