I'm not a medical professional but I have
a few years of biology behind me. When a
sperm penetrates an egg, the egg sends out
a membrane that prevents all other sperm
from entering. Thus a child has one set
of DNA from the mother and one from the
father. Any "extra" sperm leave the body
(unless there happen to be two eggs
available, thus fraternal twins).
Once a baby is brought into the world
(alive or not), that child can have only
one set of DNA.
If a woman decides to have a child with
another man then that second child's DNA
will not match the father of the first
child.
DNA evidence does not give 100%
reliability (it's based on probablilty, a
component of statistics and there are no
such things as 0% and 100%) but it gives
enough reliability that legal courts
accept it.
I hope this helps you.
Good luck.

Glad I could help. I looked at the other
"Paternity" thread and couldn't believe
the flaming! Good heavens!!
I'd never heard about a creature having
dual paternity, guess I'll have to
investigate same. AFAIK, human-wise, I
feel confident that my answer is as
correct as possible
(statistically-speaking ).

it is possible in lizards and dogs and
cats because their bodies and reproduction
systems are very different than ours are
).
