Question

Genetics Question, PLEASE HELP!

Answer 1

For the Diagram cross match between two genotypes RALPH:AB with WANDA:AO. The possible genotypes produced are AA,AO,AB,BO. Cross match between FRED and WANDA on the other hand will give out AB,BO,AO,OO. Since the baby had an O genotype the only possible answer will be FRED.

But it can't PROVE for absolute that he is the babys father because Wanda might slept around(LOL) and other possible genotype such as O or AO might given similar possiblities

For the last question other possible genotype would be AO ,OO, or BO.

FYI: A and B are dominant while O is recessive.
