Do brothers and sisters have the same DNA?
Because of recombination, siblings only share about 50 percent of the same DNA, on average, Dennis says. So while biological siblings have the same family tree, their genetic code might be different in at least one of the areas looked at in a given test. That’s true even for fraternal twins.
Can you share DNA and not be related?
Not necessarily. Even though your genealogical relationship is 4th cousins, your genetic relationship can be non-existent. You will only share DNA with your 4th cousins about 50-60% of the time. It is also possible to share a certain amount of DNA with someone who isn’t actually your cousin!
