Final answer:
George O NN could not be the father of the child with blood type AB MN because he has neither the B antigen nor an N allele required to produce the child's blood type.
Step-by-step explanation:
In this genetics scenario, we consider the ABO and MN blood type systems. The woman has blood type A MM, and her child is type AB MN. We need to discern which potential father's blood type could not be the biological parent based on the child’s blood type.
The child has one A antigen from the mother and one B antigen which must have come from the father. As such, the father must possess a B antigen. Additionally, the child has one M and one N allele, since the mother can only contribute an M allele, the father must contribute an N allele. Thus, any father without a B antigen and an N allele cannot be the biological parent of this child.
Looking at the options:
- George O NN - This individual cannot be the father as he has neither B antigen nor M allele.
- TOM AB MN - This person could be the father as he has B antigen and N allele.
- Bill B MN - This person could be the father as he has B antigen and N allele.
- Claude A NN - This person cannot be the father as he lacks a B antigen.
- Henry AB MM - This individual could be the father as he has B antigen and possibility for N allele, despite no evidence of it.
Therefore, George O NN and Claude A NN could not be the father, as they do not possess the necessary B antigen. However, George is the only one on the list who also lacks the M allele, he is the most definitive exclusion.
