THE inheritance of reproductive traits has received relatively little attention in the turkey in comparison to the chicken. Although the reports of Asmundson (1938 Asmundson (1941), Knox and Marsden (1944), Whitson et al. (1944) and Walter and Hoffman (1947) suggest that most of these characters are inherited similarly to those in the chicken, there is only limited information concerning their heritability in the turkey. Also, there are no reports in the literature regarding the genetic correlations among the various reproductive traits in the turkey. Heritability estimates ranging from −.652 to .293 have been reported for egg production in turkeys by Wilson and Johnson (1946), Shaklee et al. (1952), Blow and Glazener (1954), McCartney (1955), Kondra and Shoffner (1955) and Blow et al. (1958). For fertility, Blow et al. (1951) estimated a heritability value of .807, using twice the phenotypic correlation between full sisters. However, this value was reduced to .30 when …
