The objective of this simulation is to determine all the possible phenotypic and genotypic crosses that can occur using all of the possible Blood Types. You will need to cross with the other possible blood genotypes in order to understand how inheritance works using co-dominant alleles.

Your Blood Type (phenotype): _______________ Your Genotype:____________________

Why did the “OO” genotype get covered when combined with versions of “A, B or AB”?

What did the “A” and “B” genotypes share? Where else do you see this in nature?
