An example of codominance can be found in the response "A horse has black and white spots." In codominance, both alleles in a heterozygous individual are fully expressed, resulting in a phenotype that is neither dominant nor recessive. The presence of distinct black and white spots on the horse indicates that both color traits are being expressed simultaneously.
