  • Silly question time... TWINS

    Have been thinking about this, and i'm still no nearer an answer and its driving me mad..lol.

    Twins that "run" in families do they come from the male line or female?

    or is it totally random?

    What I am wondering is, if a gt x4 grandmother had twins and they had a sister and the sister later had twins, would the gene for the twins run in her twins as well?

    I bet you are really confused now :D

    it is so hard to try and explain what I mean... :(

    Twin - Wikipedia, the free encyclopedia

    (this is a tiny bit from the above

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


    (DZ twinning is non-identical twins - ie two eggs produced by the mother. Identical twins (MZ) are a random event.)

    The age of the mother and the number of previous children also influence the chances of twins (older mother/more pregnancies = greater chance of a multiple pregnancy)

      Not sure which side they are surposed to come from but my friends grandmother had twins, plus four other children. Two of her daughters had a set of twins, my friend(a female twin) was pregnant with twins, sadly she lost them early on.

        As I understand it, if you and a partner have a baby and the partner has twins on his side of the family, he can't influence your ovulation so you have no greater chance of having twins.

        However, that baby might inherit the hyperovulation gene from her father so she may have an increased chance of having (fraternal) twins. There are no hereditary factors for identical twins.

        So in Julie's example, if the sister of the twins inherited the gene from her mother, she could have twins and they could also pass that gene down.

        Have I confused it even more?

            I know what you mean but don't know the answer - only one set of twins in my family that I know of (my dad and his brother) so I can't really tell which way they run. In several other cases where I'm not sure whether they were twins or just enjoyed telling the enumerator they were the same age!

              I am very interested in this as both my sons have had twins and twins run in my mothers side of the family.
              BUT...Her father mum had twins so now i am a bit confused on this.

                  hmmmn piddle!!!

                  ok,

                  Mary Watchorn had B/G twins, G twin dies.
                  Has another Girl names her Sarah (the same as G twin.)

                  Sarah marries and has G/G twins I think, (will be going to check this out on Saturday)

                  what is the likelihood of Twins being born again thro the other twins or other siblings?

                  or is it just "one of those things"?

                    The only bit I can answer with certainty is that both your sons having twins will not have been through their "influence". The production of two eggs by the mother might be a fluke, or age related etc, or a tendency inherited by her from one or both of her own parents. if twins are identical that appears to be just something that happes randomly.

                    So, if you had daughters and they had twins then this could be an inherited tendency from your family, but not for your sons children.

                      Possibly more than just one of those things (unless any of the same sex twins were identical!), but not necessarily!

                        Mary (probably) has the twin gene because she had fraternal twins.

                        She (probably) passed that gene onto Sarah who had twins. If they or any of their siblings also inherited the gene then they have a higher chance of having twins.

                        If any of the siblings are boys, they may have inherited the gene but have no higher chance of having twins themselves because its the woman's ovulation that creates fraternal twins.

                        BUT they could pass that gene on to their children etc.

                        That's why it sometimes looks as though twins skip a generation

                          Ahhhh Jackie,

                          that makes some sort of sense to me.. I'm not that hot on the technical terms of it, but explained in laymans terms ish I do understand better


                          so need to now find any relations of said twins.. and also see If the Boy twin lived and produced any offspring??

                            I have twins and I was told by the docs that the younger you are when you have twins, the more likely it is to be by genetic influence, as most "natural" twin births occur in women over the age of 35 due to hormones becoming unbalanced.

                            I had twins when I was 19.
                            My father was a twin, and he also had twin brothers.
                            I haven't found any twins in my mum's family over the past 100 years.

                              As far as I understand it, identical twins are a "fluke of nature" and occur when the dividing cells "stutter" and do everything twice, within the first few hours after conception.

                              A fluke of nature...but there may be some very subtle genetic influence which makes a woman likely to do this. But it could also be a chemical influence, so at present, it really is random chance as far as science goes.

                              Inherited twins can come down either the male or the female line - both sexes carry the X chromosome which may be programmed for twinning.

                              But a male can never influence his wife's twinning, only pass on the twinning gene to his children.

                              As night owl says, that's why twins often skip a generation or more, or even maybe ten generations!

                                    My grandad was a twin of the DZ type. (he had a twin sister).

                                    None of grandad's children had twins (two girls and a boy) and none of his grandchildren have had any children yet. (two girls and four boys)

                                      So, I think I am reading this correctly... My grandad would have passed on the twin gene to his three children (possibly), but it would only affect the chances of the women having twins.

                                      Only one of the women had a girl, so it will be passed onto her, so the chances are my cousin could have twins. My other girl cousin is the daughter of the son so could it have been passed to her through her dad?

                                        No, more complicated than that!

                                        Any of the females COULD have passed the gene onto her son...who may then pass it on to any of his daughters AND any of his sons.

                                        All depends which X chromosome gets selected at each conception.
