Do Father and son have the same DNA?

The DNA in these new chromosomes provide the genetic information for the individual, the so-called genome. … 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.

Does DNA make us who we are?

A century of genetic research shows that DNA differences inherited from our parents are the consistent life-long sources of our psychological individuality―the blueprint that makes us who we are.
