The inheritance of the ABO Blood Group System is very specific, this serves as one of the first methods to determine the likelihood that the accused father is the father or not. However it is not a reliable to determine the fatherhood just by the blood group. Take this examples to explain. Mr A is not the real father but it happens that Mr. B who is the real father also got the same blood group as Mr. A. Here, Mr. A would seem to be the father based on blood group yet he is not. Another example:if the offspring blood group had taken one genotype from the mother and obviously nothing from Mr. A, chances are Mr. A is not the father. Again, there are certain conditions or syndromes which can make this untrue.The Bombay phenotype,a condition where individuals can be genetically any of the blood types is one example of exempting situation.
DNA testing gives definite answer over the controversy as the blood group system has different situations where it could give an inaccurate result sometimes.

No, Blood are divided into four groups: A, B, O, AB. (Additionally, there is a +/- factor which is added to each major group). Since the population is divided in various percentages into these four groups, you can only narrow down paternity and sometimes exclude it. E.g. If you are blood type AB, and the child is Type O, you are excluded from being the father. DNA testing from you and the child (cheek cells) are the minimum for determining paternity. Best results are DNA from both the Mother, the putative father, and the child.
Hope this helps a little.

No, but you can exclude something real obvious. For instance if you and the mother both have type O blood and the baby has type A or B, then that most certainly isn't your baby. But if you have type A blood and the mother has type B blood and the baby has type O, it could still be yours. Much easier to let the professionals handle this type of thing.

You can narrow the options by the blood type, but only a DNA test will give positive proof who the father is.

no, anybody can have the same blood type...it's the dna that determines fatherhood

Babies can have either the mom's or dad's blood group, so only DNA tests will tell fo sure who the father is.

In some cases it can lead to the father, especially if the father has a rare type, although only dna testing is failproof.

No. But a DNA test will supply the answer.
