If you have a family history, mostly a maternal history, then you are at an increased chance of having twins yourself. These are mostly dizygotic or fraternal twins and not monozygotic or identical twins. This comes from the ability to ovulate more than one egg at any given point in ovulation.
The general rules of thumb are the older the mom, the better chance of having twins. And if fraternal twins are on the women's side of the family, your odds increase dramatically as well (and as you can see, don't think that delivering one set of fraternals means you're immune from delivering a second set).

Same as any other couple of that fertility and age. Identical twins are NOT genetic. Identical twins form when one egg splits into two resulting in two embryos with the same DNA ( and is not considered to be a hereditary trait, but rather an anomaly that occurs in birthing at a rate of about 3 in every 1000 deliveries worldwide). Fraternal twins is when the mother releases two eggs that are both fertilized and don't share DNA. This is what gets passed down to her daughters to increase the chances of twins and theres no "skipping generations" etc.

The chances are low, or slim to none. Twins that occure genetically are generally fraternal. It is a genetic condition that a woman should ovulate and drop two eggs. (passed through the maternal line) This is what produces fraternal twins. There is no genetic link to being able to have a sperm split an egg in two upon fertilization making identical twins. This is just chance. They say the chances are higher should you have family members who have had identical twins but the percent is still only like >1%.

identical twins are not linked to genetics..only fraternal twins. So they have the same chances as anyone else for identical twins. If fraternal twins run on the women's side of the family then their chances are increased.

I would answer like the first poster that it skips a generation, but today on Oprah (and it was just on in the background before the news) they had a woman who was an identical twin who gave birth to identical quadruplets...without any fertility drugs or anything.

Very great I suspect. My oldest brother is a twin and married a twin. He and his wife now have 2 sets of identical twins.

from what I've heard it's VERY high compared to people of non-twin births. However, your chance for twins is elevated with every pregnancy. Also I have read if you previously given birth to a baby weighing more then 8 pounds, your chance of twins is almost doubled.

100% if they adopt twins, 0% if it is 4 gay men who do not adopt. Somewhere between 0% and 100% for the rest.

CHances are very good.. but twing generally skip a generation.. but a twin and a twin would certainly raise the odds!
