Quizplus · Accepted Answer

Genetic incomplete dominance occurs when the heterozygous genotype produces an intermediate phenotype that is different from the dominant and recessive phenotypes. In example C, the individual inherits one allele for obesity and one for thinness, resulting in an average weight phenotype that is distinct from the extremes of obese or thin. The other examples (A, B, D) do not show incomplete dominance as they result in a dominant or recessive phenotype based on the alleles inherited.
