how do you end up with twins ? Posted: 07-10-07 17:36pm
Other than fertility drugs, how do you end
up with twins, triplets, etc? I have twins
on my side of the family, but I don't know
how that all works. Does it skip
generations like baldness? Sorry to sound
like a ditz!

Twins are not too uncommon, even without
fertility drugs. There are two ways you
can naturally end up with twins.
One way is that the woman's body releases
two eggs instead of one. That means
during sex, two sperm can come in, one for
each egg. That makes two babies called
fraternal twins. They may be
female/female, male/male, or female/male.
They will look about as similar as any two
regular siblings.
The other way is that one egg meets one
sperm, but early on in development, things
just get split in half, developing into
two babies with the same DNA. These are
called identical twins. They will be
male/male or female/female. Those are the
kinds of twins that you can't always tell
apart easily.
