Study Notes
Incomplete Dominance
- In incomplete dominance, the phenotype of heterozygous individuals is a blend of the two parental traits.
- The pattern of dominance exhibited in incomplete dominance is neither allele being completely dominant or recessive.
- When a red-flowered snapdragon (RR) is crossed with a white-flowered snapdragon (WW) in incomplete dominance, the result is a pink-flowered snapdragon (RW), which is a blend of the two parental traits.
