  1. On the diagonal, in italic characters heritability estimates
  2. Upper triangle, phenotypic correlations
  3. Lower triangle, genetic correlations
  4. HP, hip-width (35-week old ducks); FI, feed intake (determined over 37 days); EW, egg weight (determined over 37 days); FCR, feed conversion ratio (determined over 37 days); DFI, daily feed intake; EP, egg production (between 226 and 329 days of age)
  5. Significant differences among groups are indicated as **P < 0.01 and *P < 0.05
