Identification of SNPs and INDELS associated with duck egg quality traits through a genome-wide association analysis.

ABSTRACT: Egg quality traits are economically important in the poultry industry. To explore the genetic architecture and identify potential candidate genes, a genome-wide association study (GWAS) was performed for 13 egg quality traits using data from whole-genome sequencing of 299 Longyan Shan-ma female ducks, including 12 quantitative traits and one qualitative trait, eggshell color (ESC; white, light green, green). From estimation of pedigree genetic parameters, heritability (h²) ranged from 0.022 to 0.996 for the 12 quantitative traits, with the highest h² (0.996) for eggshell color a* value (ESCA) and the lowest h² (0.022) for egg yolk percentage relative to EW. A total of 8,874 single nucleotide polymorphism (SNP)-based significant associations (1.0 × 10^-6
