If a white female cat and a black male cat produce offspring that are both black and white, this is an example of codominance. The reason for this is that a person who has A allele and a person who have B allele will have blood type AB. 

I hope this helps!

I believe this is an example of dominance because For instance, a person having A allele and B allele will have a blood type AB because both the A and B alleles are codominant with each other.
