A trait shows blending of characteristics. What type of inheritance is this?

Verified Answer

This type of inheritance is called incomplete dominance, where neither allele completely dominates the other, so the phenotype appears as a blend.

Key Idea

Term Meaning
Incomplete Dominance Both alleles partially express
Blended Trait Intermediate phenotype appears

Example

Cross Result
Red Flower (RR) × White Flower (rr) Pink Flower (Rr)

Genetic Representation

Genotype Phenotype
RR Red
rr White
Rr Pink (blend)

Stepwise Understanding

  1. Two parents with different traits are crossed

  2. Offspring receives one allele from each parent

  3. No allele completely dominates

  4. Both traits combine partially

  5. New intermediate phenotype appears

Important Concept

In incomplete dominance, phenotype is not same as either parent, it is a mix.

Real Insight

This is different from normal dominance where one trait hides the other, here both contribute visibly.

So blending of traits indicates incomplete dominance inheritance.
