Biology - Multiple alleles

Multiple alleles

For some characteristics, such as blood groups and the kind of coat tabby
cats have, there may be more than 2 alleles for a particular gene.
Remember, an individual will have only 2 of the alleles for that gene.
Blood groupings:

_Let I__ = allele for group A_

_Let I__ = allele for group B_

_Let i__ = allele for group O_

What are the possible genotypes and their phenotypes? Practise some
crosses of different phenotypes.
