Does father and son have same DNA?

Each son receives DNA for his Y chromosome from his father. This DNA is not mixed with that of the mother, and it is identical to that of the father, unless a mutation occurs. It has been estimated that a mutation occurs about once every 500 generations, or every 15,000 years, give or take a few millennia.

Why doesn’t my DNA match my parents?

The most likely reason that you don’t show up as a match to the parents (either or both) of your DNA match is because you are not really related to your match. This is most likely to be the case when the DNA segment you share with your match is very small, like less than 5-7 centimorgans (cMs).
