How does a blood test connect two siblings with a the same mother?

A DNA sample is extracted from a swab taken from the mouth of each sibling. The resultant DNA 'fingerprints' are compared to a sample fingerprint of the mother's DNA. They should contain half the DNA fingerprint of the birth mother.

What is a blood relationship?
A "blood relationship" means people related through a bloodline. A woman and man marry but are not related before marriage nor do they come from the same bloodline. But, you and siblings born to your mom and dad are related by bloodline. Your mother's siblings (your aunts and uncles) are direct bloodline, and the same with your father's siblings. But you do not have a blood relationship to the spouses of your mom's or dad's siblings. If a cousin is related on your dad's side, your mom and your cousin are not related by blood, because your cousin is not your mom's relative. Same with a cousin on your mother's side; they are not related by blood to your father.

Same Mother, Different Fathers ... Half Siblings:Yes, if you have the same mother but different fathers then you are half brothers or half sisters. However, if you and another sibling had the same father then you are not half siblings but brother and sister. It's the gene pool so it doesn't matter if your mother gave birth to you or not, if it's a different father then you are a half brother or half sister.No, if you have the same mother, you are not half siblings, only if you have different fathers, you are a half siblings. Nothing from the womb is half.Obviously the person who answered the question above is not very educated. This seems to be a misconception among the black community, (no offense... I'm half black myself). It doesn't matter if siblings share the same biological mother or father because you receive half your DNA from your mother and half from your father. So, to answer your question... it doesn't matter if you share the same mother or father, you're half siblings either way. Looks like the person above was sleeping in their science class or just a victim of misinformation.
