  18. The Genetics of Blood Type How can we predict Blood Type inheritance? Using a Punnett square! Let’s look at possible blood types of the children of a couple whose blood types are AB- and O-.

  19. The Genetics of Blood Type First we need to determine their genotypes. Looking at our chart, the genotype for AB- is AB-- and the genotype for O- is OO--. We need to FOIL and then draw a Punnett square. From one parent we can get A- or B- From the other we can only get O-.
