D
Explanation
Codominance is a type of inheritance wherein both alleles (forms of a gene) from parents are fully expressed in the offspring's phenotype, instead of blending or one being dominant over the other. So, an offspring would show a mixture of traits from parent organisms. Simply, a characteristic instead of being selected, displays mixed characters or properties. Considering options A through D. The concept of codominance is exemplified here by option (D). An orange cat (one parent trait) and a black cat (another parent trait) producing an orange and black kitten (offspring showing traits of both parents)- is illustrating codominance.
