How does incomplete dominance differ from complete dominance in it's phenotypic expression?

Description : How does incomplete dominance differ from complete dominance in it's phenotypic expression?

Last Answer : 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.
