INCOMPLETE DOMINANCE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How are Incomplete Dominance and Codominance different than a normal dominant/recessive cross?
A
There is no difference
B
The heterozygous genotype has a unique phenotype
C
There is no heterozygous genotype
D
There is only one phenotype regardless of genotype.
Explanation: 

Detailed explanation-1: -In complete dominance, only one allele in the genotype is seen in the phenotype. In codominance, both alleles in the genotype are seen in the phenotype. In incomplete dominance, a mixture of the alleles in the genotype is seen in the phenotype.

Detailed explanation-2: -Incomplete dominance is defined as the gene interaction that occurs in the heterozygote. On the other hand, co-dominance is defined as the relationship between two genes. 2. In incomplete dominance, the dominant and recessive allele does not dominate one another.

Detailed explanation-3: -The difference between incomplete dominance and codominance is: that in incomplete dominance, the offspring do not exhibit the traits of either parent, while in codominance, the offspring exhibit the traits of both parents.
