Question
The inheritance pattern in which there is blending of traits in the phenotype is called?
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 mask the effect of the recessive one completely.
The correct answers are: Incomplete dominance,
Complete dominance
- Incomplete dominance is observed in this case.
- The parents are red and white flowers.
- The offspring is a pink colored flower.
- The pink color is because the dominant allele of the red flower does not mask the effect of the recessive white color allele completely.

Which of the following is NOT an example of intra-genic gene interactions?
- 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.
