My husband's brothers are twins, what are the odds of us having twin babies?

Question

My husband has 2 twin brothers so I'm wondering, when we have kids, is it possible for us to have twins?

Answer 1

Your odds are the same as if he didn't have twin brothers. Even if you had twin sisters, I don't think the odds change at all. The odds of having twins in a normal instance are about 33:1, or 3%.
Your odds increase if:
You are over 45 years old.
You live in Mass. or Conn.
You, your mother, or your grandmother is a twin.
Hope I helped you, and lgood luck! Enjoy your child(ren)

Answer 2

Odds are 3%. That is the odds for everyone with no known genetic ties to twins. Since twins run on the mother's side of the family, your husband's brother having twins has nothing to do with it.

Answer 3

My Mom and I were just talking about this. The genetic tendancy for twins runs on the mother's side. Usually does skip a generation. My mother is a Fraternal Twin, so I am more likely to have them.

This is from Wikipedia.
Fraternal twins (commonly known as "non-identical twins") usually occur when two fertilized eggs are implanted in the uterine wall at the same time. The two eggs form two zygotes, and these twins are therefore also known as dizygotic as well as "biovular" twins. When two eggs are independently fertilized by two different sperm cells, fraternal twins result.

Dizygotic twins, like any other siblings, have an extremely small chance of having the exact same chromosome profile. Like any other siblings, fraternal twins may look very similar, particularly given that they are the same age. However, fraternal twins may also look very different from each other. They may be different sexes or the same sex. The same holds true for brothers and sisters from the same parents, meaning that fraternal twins are simply brothers and/or sisters who happen to have the same age.

Studies show that there is a genetic basis for fraternal twinning. However, it is only the female partner that has any influence on the chances of having fraternal twins as the male cannot make her release more than one ovum . Fraternal twinning ranges from 6 per thousand births in Japan (similar to the rate of identical twins) to 14 and more per thousand in some African states.[ citation needed]

Fraternals are also more common for older mothers, with twinning rates doubling in mothers over the age of 35. [citation needed] With the advent of technologies and techniques to assist women in getting pregnant, the rate of fraternals has increased markedly. For example, in New York City's Upper East Side there were 3,707 twin births in 1995; there were 4,153 in 2003; and there were 4,655 in 2004. Triplet births have also risen, from 60 in 1995 to 299 in 2004.

Answer 4

Fraternal twins are on the mothers side. Identical twins are a natural phenomena and an enigma that has yet to be solved.

If you have a daughter then she could inherit the hyper ovulation gene to have fraternal twins from her dad if his brothers are fraternal.
P.S. The odds increase depending on your age, race,weight and if you take fertility drugs.

Answer 5

I am proof that the twins gene does not skip a generation nor does it come from the mother's side. My husband is a twin himself - I have absolutely NO twins in my family and guess what..., I have twin girls.

If there are twins anywhere in the fmily on either side - you have a chance. I do not believe that anyone can answer what exactly your chances are. There are 13 sets of twins on my husbands side - some skip generation some do not - some of the mothers had the same blood and some did not such as myself.

I have found through research on many issues related to children's studies that some of these doctors / scientists have no idea what they are talking about -

Sorry but if someone tells you that it will not happen because it has to be on your side of the family or because it skips generations - they have not met someone to prove them wrong!

If you have twins - enjoy them before they start walking LOL

Either way I hope that he / she / they are happy and healthy :)

Answer 6

Actually, your body will be the one to cause twins, not his. Twins happen for one of two reasons: either two eggs are released and fertilized in one cycle creating fraternal twins, or one egg isn't fully divided when it is released, and both halves are fertilized, creating identical twins. Your chances of having twins are about 3 in 100, or 3%, unless you have some family history on your side.

Answer 7

none as far as I know...


Twins come from the female not the male. 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.

Fraternal twins "run in families" on the mother's side only, if she inherits the gene for hyper ovulation.

Answer 8

Don't expect to get twins because your husband's brothers are twins.

Answer 9

The same as anyone else's. Its the mothers body that determines the likelihood of twins, so your husband family does not change the chances at all.

Answer 10

if you all have a daughter then she could possibly have twins because then it would be her grandma who carried them before. it does only run on the mothers side so if your grandma carried twins then your chances go up, has nothing to do with your husband, he only determines the sex of the baby. you are the one thats ovulating the eggs, not him. good luck though!!
