Answer:

C. Incomplete dominance

Explanation:

According to the given information, the phenotype of the heterozygous genotype is different from either of the homozygous genotypes. This means that it is not complete dominance. The heterozygous genotype has one-half the number of receptors and expresses the phenotype that is intermediate of two homozygous genotypes. This is an example of incomplete dominance. In incomplete dominance, the phenotype of the heterozygote is distinct and is intermediate of two homozygotes. This occurs since none of the alleles is completely dominant over the other.
