Difference Between Dominance and Incomplete Dominance.

The main differences between Dominance and Incomplete Dominance are as follows

DOMINANCE  INCOMPLETE DOMINANCE
1. Fis similar to the dominant parent. Fis different from either of the two parents.
2. Phenotypic ratio is different from genotypic ratio Phenotypic and genoypic ratio are the same.

3 In Fhybrid, the dominant trait is completely expressed.

In Fhybrid, dominant trait is incompletely expressed.
4. A single dominant allele(e.g., Tt)is expressed fully. Two alleles (e.g., RR)are required for the expression of complete dominant trait.
