Abstract excerpt

Heterosis has been widely utilized in chicken breeding to improve economically important traits. However, few studies focused on revealing the factors contributing to egg production heterosis. In this study, White Leghorn and Beijing-You chickens were used as parental breeds to generate purebreds (WW, YY) and reciprocal crossbreeds (WY, YW) to characterize heterosis for egg production traits including age at...
