The only way to know for sure is a DNA test. This involves both brother and sister and father having this blood test done. It is not always necessary to have the father participate. Just the brother and sister alone will know if they have the same father. If you want to be sure who that father is, you will need a sample of his blood as well. The test is expensive, however. Talk to Mom or a school counselor if you need to, or wait until you are an adult to have the test done.
