Do my non identical twin boys come from my genes or their fathers?

Question

I have non identical twin boys and were're not sure where the twin thing comes from is it the maternal side or the paternal? My father has twin cousins non identical boys so I assumed they were from my line but a lot of people have said non identical twins run down the fathers line is this true? I also suffer from polysistic ovary syndrome which affects my fertility levels to be up and down and thought this could also be a factor although the doctors were never really sure on that

Answer 1

Hi ya as far as I know the gene runs through mum or dad, when I was pregnant the midwife asked me if either me or my husband had any multiple births in my family not has my husband so I assume it can be either.

CONGRATULATIONS TWINS FANTASTIC OH AND BOYS ARE MY FAV X X

Answer 2

Twins occur in two ways. One way is where two eggs are released at the same time during ovulation, and both are fertilized. This results in non-identical (or fraternal) twins. At other times, for some reason I believe is still not understood, a single fertilized egg separates into two, and each form a child. Since both babies come from identical halves of the same egg. they are, themselves, identical. Whether single, or multiple births, all offspring will have an equal amount of genetic material from both parents. If there is a genetic characteristic present in the donation of one of the parents, that characteristic may come out in some of the children, and not in others. Sometimes that feature will even skip a generation or more, and then pop up again. This particular one does seem to have passed to you through your father's line.

Answer 3

As a mother of twins, where there is NO family history ever, I asked the same question lots and have been told that it's down to the maternal line and that non-identical twins are due to higher hormones in the mother.

Answer 4

Twins have NOTHING to do with genes, not really, if your Mother or any other female member of the family, was able to drop or ovulate more than one egg at a time, then you would. Twins come about when two eggs are dropped, or when one egg splits into two. This has nothing to do with genes. Since your boys are not identical then you had two eggs that were able to be fertilized.

Answer 5

ALL of your children have both yours and your partners genes. If you had a child who only had one or the other parents genes then that would be cloning.
We have 23 chromosomes in our gametes, or sex glands and our partner has the other 23 making 46 all together with exceptions such as in the case of Down's Syndrome where there is an extra chromosome.
Children make "take after" one parent or the other and this is due to dominant or recessive genes.
Hope this helps, it's quite complicated but that's it in a nutshell.

Answer 6

Agree with the double-egg thing of course - well done you! My twin boys came about shortly after a miscarriage and my gyno said that when you miscarry, you still have a high level of the FSH hormone in your body, and that this can be responsible for mutiple egg-release.
Congrats and enjoy - mine are now nearly 8 and a real joy!

Answer 7

Fraternal twins result from the release of more than one egg during ovulation; that's something that your twins' father had nothing to do with, it's all you. The tendency to release more than one egg itself can be inherited from either side of the family, apparently (or so I've read) -- so you could have inherited your tendency to release more than one egg at ovulation from your father's side of the family. But the father of your child just isn't a factor.

Factors that are relevant to the incidence of fraternal twins:

-- the mom's genes
-- age (the incidence of fraternal twins increases after the age of 35; as women age they have an increased likelihood of releasing multiple eggs at ovulation)
--fertility drugs
--race (twins are more prevalent among certain races)
--nutrition (insofar as bad nutrition decreases the statistical likelihood of having twins)
--you've already had children
--you've already had twins
--you're a fraternal twin yourself

Answer 8

At their theory the DNA of similar twins is analogous. even with the undeniable fact that, interior the early tiers of embryonic progression each and each and every of the dual's DNA can undergo small mutations. for that reason if the DNA of similar twins is sequenced thoroughly then they received't be similar. even with the undeniable fact that, the try as used for forensic DNA diagnosis seems at ~15 to twenty positions or loci on someone's' DNA. similar twins have an identical DNA at those positions and for that reason it isn't accessible to differentiate between them. an identical checks are used for paternity attempting out. for that reason, with your problem it does no longer be accessible % out which of an identical twins became the daddy. From a legal perspective, what's exciting is that the checks could have shown that one in each and every of them is the daddy. yet that you probable can a courtroom order to pay baby upkeep? it isn't accessible to apply fingerprints to make your thoughts up which twin is the daddy.

Answer 9

Non - identical twins form from 2 seperate eggs.
It has nothing to do with the father except that 2 sperm managed to fertalise your eggs in this case.

Answer 10

The propencity to have twins comes from the mother's side of the family - unless you're using drugs to conceive. I guess that means you're more prone to ovulating more than one egg at a time.
