1
Additive effect: half the mean phenotypic difference between homozygotes for the C. grandiflora allele and homozygotes for the C. rubella allele.
2
Per cent F2 phenotypic variance explained by QTL.
3
Homozygous additive effect (2a) relative to mean phenotypic difference between C. grandiflora and C. rubella for traits that differ significantly between C. grandiflora and C. rubella.
