It won't be identical, but it will match in the sense that a large number of the DNA markers used will match indicating that they are father and son.
As for blood makeup, the only thing one can do is eliminate someone as a father or son by seeing types that don't match at all. For instance if the purported Father is AB and the purported son is O than they are not father and son, the vice versa is true also.

A son will have a very similar Y chromosome to his father's, nearly identical in fact. However, the rest of the DNA, the 22 pairs of autosomal chromosomes, will have 50% dad genes and 50% mom genes.
Blood type is inheritable, so there's a chance that a son will match his father's blood type, but only if his mother's blood type is a match, too.

A son only gets half of his genetic makeup from his father- thus there's some chance they won't have the same blood type. As for DNA, they're not the same person so they don't match exactly but they're definitely over 99% the same just to be human, male, and closely related.

Yes, any child's' DNA will show whom' the (Birth Father) truly is. All you have to do is get yourself and your son tested. I hope my information is acurate and can help you. Good luck on your JOURNEY. GOD BLESS~ Michael Guilford
