Phenotypes are calculated as means of all NILs contributing to each QTL. Dominance deviation describes the difference between the observed LH/LE phenotypes (SSC) and expected phenotype based on midparent value between the observed LH/LH and LE/LE homozygous seed set.
a
Significant deviation from the midparent expectation; positive values indicate that LH/LE heterozygotes produce more seed than expected.
