In a diploid organism, there are three different alleles for a particular gene. Of these three alleles one is recessive and the other two alleles exhibit codominance. How many phenotypes are possible with this set of alleles?

The given question can be related to human $A BO$ blood group,
where alleles $I^{A}$ and $I^{B}$ show codominance and allele 'i; is recessive.

Number of genotypes $= 6$
Number of phenotypes $= 4$
