Heritability in the broad sense ([H.sup.2] or [h.sup.2]) was estimated according to Hanson et al.
where [h.sup.2] is heritability in the broad sense; [[sigma].sub.g] is genotypic variance; and [[sigma].sub.ph] is phenotypic variance.
The extent to which a phenotype is determined by its genetic makeup (genotype) is called
heritability in the broad sense. At gene level, broad sense heritability is the proportion of the total variance that is attributable to the average effects of genes and this is what determines the degree of resemblance between relatives.
All of the heritability in the narrow sense of sire half-sib and the
heritability in the broad sense of dam full-sib of body weight, test diameter of S.
Heritability in the broad sense on parental clones evaluated over 2 yr and two locations on a single plant basis was 0.56, while introducing clonal replication increased the heritability to 0.90.
