Question
Which of the following is NOT an example of intra-genic gene interactions?
Incomplete dominance
Co-dominance
Epistasis
Multiple alleles
Incomplete dominance
Co-dominance
Epistasis
Multiple alleles
Hint:
The condition where the effect of one gene depends upon the action of more than one gene..
The correct answer is: Epistasis
- Epistasis is an inter-genic gene interaction.
- Intragenic refers to the interaction between alleles of the same gene, while inter-genic interaction refers to the interaction between the alleles of different genes.
- In case of epistasis, the expression of alleles responsible for one gene is due to the expression of one or more genes.
- Example of epistasis is fur color. The fur color of an animal depends on two genes (E and B). B gene is responsible for color while E gene determines the level of expression of the B gene.

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.
