Unless they're an identical twin, no... or at least, it's EXTREMELY unlikely. If you're female, your DNA should be 50% similar to a sister; if your sibling is of the opposite sex, your DNA will average slightly less than 50% similar (a fraction of roughly 22/46); and if you're male, your DNA will average slightly more than 50% similar to a brother (24/46) because the Y chromosome is inherited exclusively through the father.

Is your mother or father's DNA strand transcribed?
Father's DNA precedes Mother's DNA. If siblings have the same Father they are considered Whole siblings. If siblings have the same Mother but not same Father they are considered Half siblings
Why do siblings look alike?
because siblings share much of the same DNA. if the parents are the same, then each child will have half it's DNA for either parent, so siblings will share an average of half their DNA, ending up with the similar characteristics that their DNA codes for. for siblings with only one parent in common, an average of a quarter of their DNA is the same.
Is it possible that DNA of siblings born from same parents totally do not match at all?
Such an event is highly impossible because siblings receive the same set of genes from their parents. The slight differences in their DNA is due to allelic differences and due to recombinational events. However, no such event can cause a total mismatch of the DNA of two siblings from the same parents.
How do you know if you and your siblings have the same parents?
Try a DNA test with a doctor present.
Do DNA of the siblings born from the same parents match?
DNA of siblings are not complete matches of each other but show some similarity and common banding patterns. In case of identical twins, however, the DNA is a perfect match.
True or false Millions of individuals have identical DNA profiles?
False. No one, except identical siblings, have the exact same DNA profiles.
Do siblings have similar fingerprints?
Depends. If they are twins (Identical) then yes. There has been reports of Identical Twins having same DNA and Finger prints. There has never been any records of regular siblings sharing the same fingerprints
You can prove siblings are related by?
similarities in the DNA
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 DNA does?
It is the genetic matirial of all living organisms. It makes you look and act similar yet not exactly the same as your parents or siblings.
Is everbody's DNA the same?
No, everybody does not have the same DNA. DNA is your unique signature.
Can first cousins have same dna if child is tested with one cousin and test come back 99.90 is it possible that the other cousin can test higher then that or be more accurat than 99.90?
first cousins CANNOT have the same DNA. siblings share 50% of their DNA, and first cousins share 25%. I'm not sure which test you are refering to, as 99.9% DNA match would infer identical twins.
