Question
Semi-dominance or partial dominance is also known as:
Incomplete dominance
Co-dominance
Complete dominance
None of the above
Incomplete dominance
Co-dominance
Complete dominance
None of the above
Hint:
Neither of the allele is completely dominant or recessive in this type.
The correct answer is: Incomplete dominance
- Incomplete dominance refers to semi or partial dominance.
- Neither of the alleles making up the gene is dominant or recessive.
- The phenotype of the offspring will be the mixture of phenotypes of both the alleles.
- Example is cross between red and white flowers which produces pink flower in the case of Snapdragon and Mirabilis jalapa.

In case of co-dominance:
- A, B and O are alleles responsible for blood groups.
- Neither of the allele is completely dominant over other.
- Example: For a person with AB blood group, the expression of both A and B alleles occurs.
