There is no difference
|
|
|
The heterozygous genotype has a unique phenotype
|
|
|
There is no heterozygous genotype
|
|
|
There is only one phenotype regardless of genotype.

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: -contrast incomplete dominance and codominance. incomplete dominance= neither allele is dominant but are expressed. codominance= neither allele is dominant, but expression of alleles is observed as a distinct phenotype in heterozygous individual. inheritance of 1 character has no effect on inheritance of others.
Detailed explanation-3: -In codominance a heterozygous individual expresses both simultaneously without any blending. An example of codominance is the roan cow which has both red hairs and white hairs. In incomplete dominance a heterozygous individual blends the two traits.
