Pregnancy Info HOME

From what I've read on this board, the probability of twins runs through the mothers genes.

From what I heard and it may sound suprising everything dependes on father sides So if he has twins in his family you have big possibilities of having twins.

i think that men cannot produce twins, however, his daughter can. whatever is in the system to make you have twins the girl will carry. but who knows really. ex, my aunt and uncle, she has no twins on her side, but he does , she had twin girls identical.

I understand that it is the mothers side which influences 'twinning'. I am 18 wks pregnant with twins and i have twins on both sides of my family, my mother has has alot of twins on her side and my father is a twin..... so who really knows, and lets face it, sometimes a miricle just happens !!!

Well I am having twins and it doesnt run at all in my family but my boyfriend has 2 sets in his family. I thought it ran on the mothers side but I guess it goes both ways. I think it skips a generation though so in your case I dont think you would produce twins. But I could be wrong!

my sister and i both have naturally conceived non-identical twins and we have recently given the QLD university genetic material so they can work out where the "twin gene" comes from. they also took genetic material from my mum and dad. at this stage there is no clear evidence where the twin gene comes from. if anyone on this site is in australia and wants to take part in this study they are trying to get as many sister pairs as possible. the twins must be non-identical and naturally concieved. interestingly there really arent many twins on either side of our family.

I have a question for those of you that may know the answer.... My husbands grandmother had twin boys on her third pregnancy and my grandmother had twin boys her third as well I am on my third pregnancy what are my chances of carrying twins? Just an anxious mommy

The father doesn't have anything to do with twins.. it's the mother who pa__ses that on to her daughter. However, that does not mean that because there aren't any twins on your mom's side, that you won't have any. Sometimes, it just happens.... but it won't be because of the father.

I know that fraternal twins only runs on the mothers side. Think about it....fraternal twins, takes two eggs. Identical twins, I am not sure. I have not found any info on it...I was curious because I am pregnant with identical twins and their father has identical twin brothers but none in my family.

bridgett - i've heard exactly what you said. it runs on the woman's side - two eggs - only produced by the woman. i am 10 weeks with fraternal twins (a__suming for now they are fraternal bc there are two sacs). but as for identical twins, i have read they are just purely by fluke, or blessing :).

When I was in the tenth grade I asked the exact question to my Anatomy and Physiology teacher and he said having twins has nothing to do with the father's gentics it all depends on if the mother inherited the trait from her mother.

ok i have a question if a women has fraternal twins. Is it possible for one of the twins to have one father and the other fraternal twin to have a different father?

Sadly, If the mother had s_x with two different men around her ovulation time, it is possible that fraternal twins could have different fathers.

how do u know and can u know if u will have twins?

i want twins. my mom had twins which makes them my twin brothers. they are fraternal. they are 9 years older than i. i have had only single births. i have 3 boys.i will be 25 on 10-26. does anyone know what my chances are to conceive twins?

Not likely at all -- because twins are a result of either the woman 1)releasing more than one egg per cycle, or 2)the egg splitting into two soon after fertilization. It's all about mom and/or her eggs -- sperm doesn't affect twinning rates.
