Explain why blood typing may not be a viable method of determining which baby belongs to which parent?

There are AB, A, B, O type blood (asides from the positive and negative).





If you were to test by that logic then 1/4 of the people in the entire world are the people your baby belongs to.





Blood typing is not hereditary, it is random among people. The best way to tell is by a DNA test.Explain why blood typing may not be a viable method of determining which baby belongs to which parent?
Blood types can be A+, A-, B+, B-, AB+, AB-, O+, and O- That's only eight possiblities, not exactly a unique modifier.





Also, the + factor, and the A, or B gene are dominant. A parent can have one gene for +, and one for -, and the blood type will show +. Likewise, an A, or B parent could have one O gene, and still come out as either A, or B. While each parent has two genes for ABO, and two genes for +-, they pass only one from each parent on to the child. If they pass the recessive one on, there is no trace of their contribution to the child's blood type.





So, let's assume there's a woman who works as a prostitute. She's blood type A+, and has clients who are A-, O-, and AB-





She gets sexually involved with her pimp, who is a B+ guy, and they have a kid. The child gets her recessive O gene, her recessive - gene, the guy's recessive O gene, and the guy's recessive - gene. This baby comes out as type O-. She does it again with the pimp, and the child gets her dominant A gene, her recessive - gene, his dominant B gene, and his recessive - gene. The second baby comes out as AB- Another time with the B+ guy, and the child comes out as A-.because of her dominant A gene, and their recessive - gene.





Her, and all her partners happen to have the same health insurance. One day, when business with his other hos is going poorly, the pimp robs his doctor's office, and gets all the medical information. Now that he knows the blood types of all the people, he sees that every time, the baby's blood type matches one of theirs, not his. He gets angry, because she's supposed to use protection when she sleeps with her clients, and he beats her until she agrees to sue the guys for child support, even though she knows she did use protection every time.





During the proceedings, she gets arrested for prostitution, and is forced into counselling, where she realizes her pimp has been abusing her, and after a lot of thought, she decides the client that was AB- was actually a very loving, and kind man, as fars a perverts go. So, she gets engaged to him, and they have a child...





her former pimp gets so mad with her that he breaks into her house, kills her fiancee, and brutally rapes her just an hour after this child was concieved. Now she doesn't even know which father the child belongs to, but if it's the pimp's she wants to get it aborted right away. The blood test comes back as being B+... B from the dominate B gene of her AB- lover, and her recessive O gene. + from her Dominant + gene, but she doesn't know that, so she has the child aborted. Yay blood type testing, so reliable!





To be totally fair, there have been some advances, which make it possible to guess that the recessive O gene may be present in a sample, but the process is still expensive, and not totally reliable.Explain why blood typing may not be a viable method of determining which baby belongs to which parent?
There are a small numbers of blood groups, with a high possibility that two people can share the same blood group. Genetic fingerprinting is a much better method of determining the parent as each finger print is unique and individual..
Because lots of people have the same blood type. It is not a unique identifier.
