Statistically, you are likely to share 25% of your DNA with your aunt. The precise division of genes in mitosis is fairly random; your match could be anywhere from very low number to 50%. Or greater, depending on how close your other relatives are.

Assume, for example, that your mother and your aunt are sisters. (The math would work almost the same way if your aunt is your father's sister.) The genetic match could be 100%, if your mother and aunt are identical twins, to something close to zero. Statistically, they are likely to share somewhere near 50% of their DNA. I assume that your parents are entirely unrelated, which probably is not perfectly true, as we all ARE "cousins under the skin", if you go back far enough. So the average of 50% from one parent and zero percent from the other indicates that statistically, you are probably somewhere near 25% related to your aunt.

If your parents come from fairly similar ancestral stock - for example, both Irish or both Japanese, or even just both European or both African - then the percentage of common DNA would be some unknown value higher. It's certain that before the industrial era of cheap transportation, your great-great-grandfather almost certainly married his distant cousin. And maybe not all that distant, depending on the size of their village!

If your aunt is an "in-law" relative - for example, if your aunt is your father's brother's wife - then the percentage of match could be quite low. Again, this would depend on how far back you share a common ancestor.

Do a step aunt and a niece share the same DNA?

Yes , your great aunt and your niece will share some but not all of your DNA. In fact, you will probably share much less than half with either of the, That is, of course, assuming that your great aunt is directly related to you, and not your aunt by virtue of being married to your great uncle.


How much DNA would a aunt share with her sister's child?

An aunt would share approximately 25% of her DNA with her sister's child. This is because the aunt is the sibling of the child's parent, and the child inherits half of their DNA from each parent. Since the aunt shares 50% of her DNA with her sister, the aunt's contribution to the child's genetic makeup is about a quarter.


Are there people with identical DNA aside from identical twins?

No, due to the random combination of genetic material during sexual reproduction, it is extremely rare for two individuals to have identical DNA. Identical twins are the only naturally occurring individuals who have the same DNA.


Can DNA differ between aunt and mother?

Your mother and her sister will have around half the same DNA on average. However, averages are strange things, in theory they could share 100% ie be identical twins or they counld share none!

Do you and your aunties share how much blood?

The first thing to understand is that "blood" is metaphorical. You don't "share" any actual blood.Statistically, siblings are related genetically by 50% ... each child gets 50% of each parent's DNA (it's random which 50%), so on average you'd expect that about 50% of your mother's DNA is identical to that of her sister.You get half your DNA from your mother, so (again statistically) you'd expect that 25% of your DNA is identical to that of your aunt.It's complicated slightly because it's possible (but statistically extremely unlikely) that your mother and aunt have entirely different DNA, but on average you can expect to be about "25% related" to your aunt because you're 50% related to your mother (always true) and she's 50% related to her sister (on average).
