- Observation A major dominant gene for hue is segregating in gerbera, accounting for -0.66 of the total variation.
- Observation The genotypic mean of the aa genotype is 32 degrees.
- Observation The genotypic mean of the bb genotype is 71 degrees.
- Observation The a allele is dominant to the b allele in gerbera flower hue.
- Observation The a allele has a frequency of 0.55.
- Observation The residual parent-offspring correlation estimate is 0.2.
