Genome-wide association study reveals distinct genetic regulation of eggshell bubble and gas pores in dwarf layers, indicating independent pore systems tied to calcium binding.

Key Points

To investigate phenotypic relationships between eggshell gas pores and bubble pores and identify the underlying genetic loci regulating bubble pore traits.
Measured gas pore quantity, mammillary quantity, and multiple bubble pore metrics in eggs from 40-week-old Brown-Egg Dwarf Layers.
Conducted phenotypic correlation evaluations alongside a genome-wide association study (GWAS) utilizing whole-genome resequencing data and KEGG pathway enrichment.
Gas pore quantity significantly correlated with mammillary quantity (r = 0.59, P < 0.01), whereas neither metric correlated with bubble pore indicators (P > 0.05), indicating two independent pore systems.
GWAS detected 32 suggestively significant single nucleotide polymorphisms associated with bubble pore traits, pinpointing candidate genes including ANXA10, CDH10, and PCDH10 enriched in the calcium ion binding pathway.
