i have a brother who had a son with his ex and my father wants to have them tested just to be sure.all the while i thought it would just be the father and the son who will undergo the test, but when i called up st.luke's, they said that the mother should also be tested. why is the mother so important?

Maternity is never in question, but testing the mother just makes it easier to do a paternity test. They run her DNA and then the child's. The child's will have gaps (the father's genes) and then they run the fathers to see how well the his DNA fills in the blanks as it were. DNA has to be a perfect match.

The Child has both the mother & father's DNA, so the mother has to be tested to get a more acturate test. That way when they test the child they can separate which genes the child got from the mother & which ones came from the father.

The DNA of the father is not the same as the son, just close
The mothers DNA is in there too, and must be a factor

I heard it's to prove she didn't switch the babies. If she didn't want his DNA to match, she could bring a friends kid and have them tested and it would be negative. This way, they test the mom and baby then match them to prove the baby is hers then match the dad.
