Question
In incomplete dominance __________________________.
Phenotype of both the alleles is expressed in progeny.
Phenotype of only one allele is expressed in progeny.
Phenotype of none of the alleles is expressed in progeny.
Phenotype of both the alleles is partially expressed in progeny.
Phenotype of both the alleles is expressed in progeny.
Phenotype of only one allele is expressed in progeny.
Phenotype of none of the alleles is expressed in progeny.
Phenotype of both the alleles is partially expressed in progeny.
Hint:
In incomplete dominance, none of the allele is dominant on the other allele.
The correct answer is: Phenotype of both the alleles is partially expressed in progeny.
- In incomplete dominance, the phenotype of both the alleles are expressed in the offspring.
- Here, no allele acts as the dominant one and suppresses the expression of the other allele.
- The offspring will have a phenotype that is a mixture of both the alleles.
- Example of incomplete dominance is the cross between red and white flowers which produces pink flower which is an intermediate phenotype in the case of Mirabilis jalapa and Snapdragon.
