Abstract excerpt

Eggshell color is an important economic trait in poultry. In green-eggshell chickens, eggshell color intensity is primarily determined by the amount of biliverdin deposited in the shell, but its genetic basis remains unclear. In this study, 230 Dongxiang green-eggshell chickens at 29 weeks of age were genotyped for the green-shell locus. Homozygous green-shell individuals were identified and subjected to a...
