Abstract Background Copy number variations (CNVs) are a major type of structural genomic
variants that underlie genetic architecture and phenotypic variation of complex traits, not …

There have been several genome-wide association study (GWAS) reported for carcass,
growth, and meat traits in chickens. Most of these studies have been based on single SNPs …

Background Body weight (BW) is an economically important trait in the broiler (meat-type
chickens) industry. Under the assumption of polygenicity, a “large” number of genes with …

This study was designed to perform an association analysis and identify SNP markers
associated with production traits of Japanese quail using restriction-site-associated DNA …

Abstract Background The Russian White is a gene pool breed, registered in 1953 after
crossing White Leghorns with local populations and, for 50 years, selected for cold tolerance …

Egg production is an important economic trait in layer ducks and understanding the genetics
basis is important for their breeding. In this study, a genome-wide association study (GWAS) …

Production animals are constantly subjected to early adverse environmental conditions that
influence the adult phenotype and produce epigenetic effects. CpG dinucleotide methylation …

Characterizing the genetic variation underlying phenotypic traits is a central objective in
biological research. This research has been hampered in the past by the limited genomic …

Background Poultry breeding programs have been focused on improvement of growth and
carcass traits, however, this has resulted in correlated changes in internal organ weights …

Egg production is the most important economic trait in laying hens. To identify molecular
markers and candidate genes associated with egg production traits, such as age at first egg …
