Overview

Genome-wide association study finds significant SNPs and candidate genes linked to egg production in Wuhua yellow chickens, suggesting pathways for selection.

Key Points

871 significant SNPs were identified, linking genetic factors to egg-laying performance traits in Wuhua yellow chickens.
Heritability estimates ranged from 0.10 to 0.38, indicating varying genetic influences on traits such as age at first egg and egg number.
Key genes SCUBE1 and KRAS regulate age at first egg through metabolic pathways, while IGF1 and PTK2 influence clutch size and egg number.
Functional analyses emphasize the role of identified genes in critical biological pathways related to egg production traits.
