Description Six single crosses and 6 reciprocal crosses were produced in the fashion of a modified diallel using 4 White Leghorn strains. Sires (20) from each strain were mated with 20 dams from each of the other 3 strains simultaneously. General combining ability was more important compared to other measures of genetic variability in the inheritance of all the traits considered except for egg weight. Specific combining ability appeared to be important only for body weight at 500 days of age and yolk index. Significant maternal effects were evident for egg production to 280 and 500 days of age, egg weight, yolk index and shell thickness. Sex-linked effects were important for body weight at 280 days of age, egg production to 260 and 280 days of age and average egg weight.
