Superfecundation
Superfecundation occurs when fraternal
twins have different fathers. These twins
are the most disparate genetically, since
they are, in essence, "half-siblings" to
one another. In this type of twinning, a
woman releases two eggs, each of which are
fertilized by a different man's sperm. In
the early 1900's, such a case occurred
when an African-American woman gave birth
to twins--one African-American, one
mixed-race. She affirmed that she had two
lovers--one African-American, the other
white.

actually I think that's what happened to
my friend, plus we think the boy was a
month smaller than the girl (I know, lucky
on the gender thing). If you look at them,
they both look like their mother, but
definitely different in some aspects.

fraternal twins can have 2 different
fathers
identical twings have the exact DNA and
can not have 2 diff dads.

plus identical twins obviously are the
same gender... that's why you never see
conjoined twins with one being boy and the
other girl (sry, conjoined twins just
intrigue me so much)

actually there have been extremely rare
cases where identical twins have come out
different gender. however it has to do
with a chromosomal defect. rarely rarely
ever happens though
