    It says Craigs blood type is AA so even if the mom is BO (O for simplicity sake) the child would be blood type A, not O. It's probably B but if you want props from your teacher you should propose that the child could have the bombay phenotype depending on how they did the test.

    b. the youngster won't be able to be Craig's. he's AA, so each newborn he produces receives the A allele from him. that is dominant, so the youngster isn't variety O. Susan might want to have a form O newborn, see you later as she is BO.

  • He could be Chimera with two DNA types. Either way, he needs to demand a paternity test to make sure.

  • D. You don't know Craig's blood type. Since it's type B, the alles can be IB and i, or it can be IB and IB. Trust me on this own.
