Incomplete dominance occurs when

Incomplete dominance (also called partial dominance, semi-dominance or intermediate inheritance) occurs when the phenotype of the heterozygous genotype is distinct from and often intermediate to the phenotypes of the homozygous genotypes. For example, the snapdragon flower color is homozygous for either red or white.

the phenotype of the heterozygous genotype is an immediate of the phenotypes of the heterozygous genotypes.

Explanation:

Each of the alleles are partially expressed

i would say the prokaryotic cells the prokaryotic cells are less complex, are usually found only in unicellular organisms and have more limited capabilities than eukaryotic cells.
