Question
If the traits of two alleles blend and express, then the inheritance pattern is:
- Incomplete dominance
- Co-dominance
- Complete dominance
- None of the above
Hint:
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.
