Association of a single nucleotide substitution in intergenic region of chromosome 4 with traits of egg quality in domestic chickens

Association of a single nucleotide substitution in intergenic region of chromosome 4 with traits... The association of SNP2-1 with egg quality traits in domestic chickens was analyzed. SNP2-1 alleles were significantly associated with the thickness of eggshells in chickens of the UK-72 line. The substitution of the SNP2-1 allele T for the C allele had an effect of 35 ± 15 μm, which corresponds to one standard deviation. For this trait, the effect of the T allele was dominant. SNP2-1 was also associated with other traits, including shell weight, egg-laying capacity in 60-week-old chickens (line UK-72), and egg weight in 60-week-old chickens (line cross CD). Thus, the QTL marked with SNP2-1 has a pleiotropic effect that depends on the chicken strain. Candidate genes located on chromosome 4 in close vicinity of SNP2-1 are discussed. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Genetics Springer Journals

Abstract

The association of SNP2-1 with egg quality traits in domestic chickens was analyzed. SNP2-1 alleles were significantly associated with the thickness of eggshells in chickens of the UK-72 line. The substitution of the SNP2-1 allele T for the C allele had an effect of 35 ± 15 μm, which corresponds to one standard deviation. For this trait, the effect of the T allele was dominant. SNP2-1 was also associated with other traits, including shell weight, egg-laying capacity in 60-week-old chickens (line UK-72), and egg weight in 60-week-old chickens (line cross CD). Thus, the QTL marked with SNP2-1 has a pleiotropic effect that depends on the chicken strain. Candidate genes located on chromosome 4 in close vicinity of SNP2-1 are discussed.
