Need an answer to the question "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 with this set of alleles?" Take a look at the answers and our detailed explanations to gain a deeper understanding of this question.

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 with this set of alleles? | HIX Tutor

This problem is similar to the problem of blood types. In blood types there are three possible alleles. Two are codominate A and B. One is recessive O . These results in four possible phenotypes 
AB = AB
AA = A
AO = A
BB = B
BO = B
OO = O 
This gives four possible phenotypes.
