^aEstimates of heritability are on the diagonal, genetic correlations above the diagonal, and residual correlations below the diagonal
^bEgg weight for first three eggs (eE3), at early (eEW) and late age (lEW), shell colour for first three eggs (eC3), at early (eCO) and late age (lCO), albumen height at early (eAH) and late age (lAH), yolk weight at early (eYW) and late age (lYW) puncture score at early (ePS) and late age (lPS), ePD and lPD are egg production rates (ratio of the number of saleable eggs to number of days in lay) body weight at late age (lBW), age at first egg (eSM)
