Question

If the traits of two alleles blend and express, then the inheritance pattern is:

  1. Incomplete dominance
  2. Co-dominance
  3. Complete dominance
  4. None of the above

hintHint:

If the inheritance blend and express themselves it is called incomplete dominance.

The correct answer is: Incomplete dominance


    • When one of the two alleles is not completely dominant over the other it is called incomplete dominance.
    • In this case both the alleles express themselves i.e, there is a phenotypic blending.
    • For example the heterozygous phenotype in arrhenium flowers is pink and its dominant colour is red and recessive is white.
