What is the difference codominance and incomplete dominance?

incomplete dominance - The situation in which the phenotype of heterozygotes is intermediate between the phenotypes of individuals homozygous for either allele.

codominance - The situation in which the phenotypes of both alleles are exhibited in the heterozygote because both alleles affect the phenotype in separate, distinguishable ways.

incomplete dominance are more likely mean blend, like you make juice contain apple and pear by blender, you can not distinguish them.

codominance can be think as mix, like you a salad that contain apple and pear.

like the example of incomplete dominance: pink flower, pink is differ from white and red, but it related to the two color,

as the example of codominance ABO blood type, blood type AB means it contain A antigen and B antigen, we can distinguish them

since there are no options posted i'll give you a few examples.

a dolphin's flipper, bird's wing, cat's leg.
