From: Inheritance of the duration of fertility in chickens and its correlation with laying performance
Genetic relationship between fertility duration day (FDD) and laying performance. FDD35 and FDD60 represent FDD measured at 35 and 60Â weeks of age, respectively. Estimates of genetic correlations are shown above the diagonal. Scatter plots of the estimated breeding value (EBV) between two traits are shown below the diagonal. The diagonal shows the histogram of each trait. Estimates of heritability and their standard error for each trait are presented on the diagonal
