do only 2 punnet squares. you recognize the alleles for the AB verify is I^A and that i^B. it extremely is the only threat for AB blood varieties. The B verify can the two be I^B and that i^B or I^B and that i (the O allele). Remeber that the I^A andI^ B alleles are codominant so the guy could phenotypically show the two alleles if he/she has the two. The O allele is often recessive and is not any longer phenotypically expressed while paired with I^A or I^B. the only thank you to get somebody with an O bloodtype could be for the two father and mom to have the O (or i) allele, so not one of the youngsters on your issue would desire to ever have O bloodtype. possibilities contain AB, B, and A bloodtypes.
