Explanation:
Restriction enzymes basically used in genetic engineering. Particularly in recombinant DNA technology. Restriction enzymes have two properties, which are very much useful in recombinant DNA technology.
First, they cut DNA into fragments or small pieces. This cutting is done to make the size of the DNA into a suitable one for cloning purposes.
Second, many restriction enzymes make staggered cuts that create single-stranded glutinous ends. These ends are favorable to the formation of recombinant DNA.
The mother has the alleles A and M, given that her blood type is A MM. Since the child has blood type AB MN, then the child has the alleles A, B, M, N. However, the alleles B and N, cannot have come from his/her mother and must have come from the father. Therefore, we are looking for a father with the alleles B and N. Based on this conclusion, the child's father is either Tom (with blood type AB MN) or Bill (with blood type B MN).
