Key differences, features, and comparative analysis of Feature and Incomplete Dominance.
| Feature | Incomplete Dominance | Co-dominance |
|---|---|---|
| F₁ phenotype | Intermediate (blend) | Both alleles expressed together |
| Example | Snapdragon / Mirabilis jalapa: Red × White → Pink | Human ABO blood group (Iᴬ & Iᴮ) |
| F₂ ratio | 1 : 2 : 1 (Red:Pink:White) — phenotype = genotype ratio | Depends on cross; both antigens appear (AB) |
