The correct explanation for Sam's blood group being AB+ while his father's blood group is A+ and his mother's blood group is B+ is:
**B** combination of different genes for the blood of parents during reproduction.
In this case, the A and B alleles are codominant, meaning that when both are present (one from each parent), the resulting blood group will be AB. Hence, Sam has inherited the A allele from his father and the B allele from his mother, resulting in the AB blood type.
**B** combination of different genes for the blood of parents during reproduction.
In this case, the A and B alleles are codominant, meaning that when both are present (one from each parent), the resulting blood group will be AB. Hence, Sam has inherited the A allele from his father and the B allele from his mother, resulting in the AB blood type.
