Blood Type
Blood Type
Since blood type of a child is inherited by the parents, it can be used to disprove paternity in some cases. For instance, if a mother's blood type is AB and her child's is also AB, then the child's father must be either A, B or AB. Therefore, if an alleged father is type O, he can be excluded as being this AB-type child's father. On the contrary, however, blood type is not a reliable method of proving paternity. Since a person can have only one of four different blood types, it could be very possible that two alleged fathers of a child actually have the same blood type, say A-type for the case described, but only one will obviously be the child's father. In this case, only a DNA paternity test could accurately determine which man must be the child's father.
Paternity Determination

When many people think of a DNA test, they may envision a desperate mother trying to figure out who her child's father could be. In many cases, yes, DNA tests are used to resolve doubts. However, now that DNA testing has been recognized as having so many applications and is so widely available to the public, many people are taking part in tests for reasons other than verification of paternity. Ironically, though, some people have uncovered hidden truths of non-paternity. Adult siblings trying to map their ancestral lineage have actually found out that they have different fathers, when it was never a question that they might.
Determine Paternity

Parents of children with rare genetic disorders, who must both carry a gene for their children to inherit the disorder, find that the "father" actually is not a carrier. There are other scenarios where people not seeking to establish paternity, actually discover non-paternity issues. So, obviously non-paternity is not restricted to those people who undergo DNA paternity tests. And, as science and DNA testing continue to advance and become more commonplace, more and more people may uncover unexpected family secrets.
