Can siblings have different ancestry 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 have a different ethnicity than your parents?

So yes, it is definitely possible for two siblings to get pretty different ancestry results from a DNA test. Even when they share the same parents. DNA isn’t passed down from generation to generation in a single block. Not every child gets the same 50% of mom’s DNA and 50% of dad’s DNA.

We get more or less than exactly 25% from each person in a grandparent pair. It’s the total of the DNA of both grandparents that adds up to 50% for the couple.

Can DNA ethnicity skip a generation?

Dna cannot skip a generation but flaws in a parent’s testing scan can make it appear so. A flaw can make it appear that there is a false break in a person’s segment, which leaves the two segments too small to read as a match.
