A trait that exhibits incomplete dominance, is one in which the heterozygous offspring will have a phenotype that is a blend between the two parent organisms. An example of this is when a homozygous red sweet pea flower crossed with a homozygous white sweet pea flower, their offspring will be heterozygous and have the pink phenotype, rather than either red or white. So, the homozygous red flower will be red, the homozygous white flower will be white, and the heterozygous flower will be pink. So there are three possible phenotypes in incomplete dominance. There are also no dominant or recessives genotypes.
Two
When a heterozygous genotype (two different alleles) results in an intermediate phenotype, this is either codominance or incomplete dominance. If it is codominance, then both alleles are expressed together in the phenotype. If it is incomplete dominance, the two alleles produce a blended phenotype rather than both alleles being expressed together.

When both alleles contribute to the phenotype of a heterozygous the alleles are said to show the dominate alleles and sometimes the recessive but mostly the dominate alleles
Incomplete Dominance
When a heterozygous genotype (two different alleles) results in an intermediate phenotype, this is either codominance or incomplete dominance. If it is codominance, then both alleles are expressed together in the phenotype. If it is incomplete dominance, the two alleles produce a blended phenotype rather than both alleles being expressed together.
Incomplete Dominance
It is called codominance or incomplete dominance.
Incomplete dominance
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.
Codominance and incomplete dominance can only exist if the genotype has heterozygous alleles.

Complete Dominance: Where in the dominant gene completely masks the effect of the resesive gen in heterozygous conditions. Ex. Tt or Rr. Incomplete Dominance: When 2 or more alleles influence a phenotype. Ex. Flowers. Codominance: When both alleles for a gene are expressed in heterozygous offspring. Ex. Bloodtype.

This is called codominance in this case, neither allele is dominant over another, it creates in heterozyogous individuals a phenotype that is not in intermediate, nor the phenotype either of the two alleles create, but rather, a different phenotype.
