I’ve heard it “skips a generation” and that there are things you can do to up your chances of having twins. So my guess is that there really is one. haha. My sister and I are identical, not fraternal. = )

I was recently wondering about this and googled it – found this, which seems to make sense to me:

<h3>Is There a “Twin Gene”?</h3>

Of the factors that influence multiple birth, there is only one that could be identified as genetic or explained by family history: hyper ovulation. Hyper ovulation is the tendency to release multiple eggs during ovulation, increasing the chances of conceiving dizygotic (or fraternal) twins. So, in families where the women have a gene for hyper ovulation, genetics would sufficiently explain an increased presence of fraternal twins.

However, only women ovulate. So the connection is only valid on the mother’s side of the family. While men can carry the gene and pass it on to their daughters, a family history of twins doesn’t make them any more likely to have twins themselves.

Yah fraternal twins are genetic… but I believe identical twins are not.

I’m an identical twin, and both me and my brother were pretty good kids!  So it wasn’t so bad to have two of us, I’m told. 🙂

@Mr. Bee: I always heard the opposite! I thought fraternal twins were random chance and identical twins were genetic :p ..

And I’ve also heard the “skips a generation” thing too..

My mom is a fraternal twin. Which means if all the above are true, there is a good chance I would be having twins! (Although I actually kinda like the idea of twins)

Mr. Bee is correct!

Identical twins (Same DNA) is the division of the fertilized egg after conception and that is just a fluke experience. Whereas fraternal twins (separate DNA) is the fertilization of two separate eggs and in order for this to occur a woman needs to release more than one egg at a time and there is a genetic pre-disposition to do so.

My mom is also a fraternal twin but the idea of twins scares the poop out of me!

As far as the twins skipping a generation this is only true if the trait is passed on to boys (because they cannot express the trait only carry it) so technically our mothers could release multiple eggs at ovulation but fertilization of more than one egg at the time of conception did not occur as our mother’s did not have twins also.

Identical twins only happen when the sperm splits into 2 once it enters the egg.

I want twins like nobody’s business! It would have been really cool to be a twin!

If you’re on the pill, you are also more likely to have twins (fraternal) if you get pregnant immediately after stopping.

The tendency of producing fraternal (dizygotic) twins can be inherited because one can inherit the ability to ovulate more than one egg at a time. However, identical twins (monozygotic) is a spontaneous event. One egg, one sperm and the egg splits in two during one of the early cleavages. When I tell students this, I usually have someone insist identical twins runs in the family. Well some people hit the lottery more than once too!

FI’s bro and sis are twins. We also have twins on my dad’s side of the family.

I’d be happy either way though. I’ve heard so many stories of people who desperately try to have ONE baby. I think I’ll take what I can get!
