Which of the following are examples of codominance?

I. A person with blood type AB

II. A flower that displays a red and white spotted phenotype (both colors are attributed to the same gene; homozygosity for either color makes a flower that is completely red or white)

III. A flower that displays a pink phenotype (a homozygous dominant flower is red and a homozygous recessive flower is white)

IV. An organism whose heterozygous phenotype is identical to the homozygous dominant phenotype
