I don’t have the picture, so I can’t say for sure — but here’s how to tell from the pattern:
- Uniform intermediate color across the whole petal (e.g., red × white → pink everywhere): that is usually incomplete dominance (heterozygote gives blended phenotype).
- Both colors clearly present at the same time (distinct patches, stripes, or speckles of pink and yellow): that can be codominance or, more commonly in flowers, a somatic mosaic/chimera or transposon-induced variegation.
- Codominance means both alleles are expressed in the same tissue (you see both pigments).
- A chimera or transposon effect produces sharp sectors or streaks because different cell layers have different genotypes or gene activity; these patterns can be clonal and unstable.
How to distinguish them experimentally:
- If vegetative cuttings keep the same pattern, that suggests a stable chimera.
- If selfing or crossing gives predictable Mendelian ratios (and a uniform intermediate in heterozygotes), that suggests incomplete dominance.
- If offspring show both parental colors separately (not blended) in predictable ratios, that suggests codominance.
If you can upload the photo or describe whether the colors are blended or in sharp patches/stripes, I can give a specific answer.
