A man dies, he's got a daughter and a nephew, the son of his brother.
Because of the inheritance an alleged son drops by, claiming to be the
son of the
man by a misstress.
Whom should they check besides the alleged son.
a) the mistress
b) the nephew
c) the daughter
I thought the nephew because of the y-chromosome wich have to be
identical.

Your friend is right. Even given the Y chromosome, we're only talking
about one chromosome, out of a total of 46. On the other hand, two people
with the same father, but different mothers, could be expected to share
12.5% of their chromosomes in common. If they had the same mother and
father, that figure would rise to 25%.
