1. Heritability estimates for hatchability of fertilised eggs were obtained from four White Leghorn strains and their crosses. 2. Based on the variance of the full-sib family means, the heritability estimates for pure-bred, cross-bred and for the combined data were 0.lb186 ± 0.lb105, 0.lb065 + 0.lb021 and 0.lb088 + 0.lb005, respectively: the results showed absence of non-additive genetic variance for hatchability. 3. Fertility was influenced more by sire strain than by the dam while hatchability was primarily influenced by the dam strain. 4. The sire x dam interaction effect was significant for fertility but not for hatchability. 5. Fertility was influenced by crossing two divergent strains. |
