Question
If the traits of two alleles blend together and express then the inheritance pattern is:
Incomplete dominance
Co-dominance
Complete dominance
None of the above
Incomplete dominance
Co-dominance
Complete dominance
None of the above
Hint:
Dominant allele does not suppress the expression of the recessive allele.
The correct answer is: Incomplete dominance
- If the traits of two alleles blend together and then express themselves, the inheritance pattern is called as incomplete dominance.
- Here, dominant and recessive genes are present. But the dominant gene does not suppress the action of the recessive gene completely.
- The offspring will have a phenotype that is a mixture of both the alleles
- Example of incomplete dominance is a cross between red and white flowers which produces pink flower which is an intermediate phenotype in the case of Mirabilis Jalapa or Snapdragon.
