Yes. Fraternal twins are due to two eggs being released.
No - If they are on either side of the family, the incidence of twin pregnancy is increased, whether they run on the mum's side or the dad's side. And in addition to the above answer, fraternal (non-identical) twins are due to two different eggs being fertilised by two different sperm.
Identical twins happen by chance only; 4 per 1000 births or 0.004 probability. Fraternal twin probability is increased only if it is on the mother's side; so this does you affect your circumstance (from what you have stated). The chance of fraternal twins is 1 in 60 or 0.017. So, your probability of identical twins is 0.004 and fraternal twins is 0.017 (BTW, I have triplets).
twins skip a generation, but according to statistics, either female or male may produce them
Fraternal (non-identical) multiples caused by the mother releasing (or being implanted with) two or more eggs… the father has no influence in the connection fraternal multiples! Identical multiples are just a miracle of nature when the egg splits two or more times, it is not generally considered a genetic trait. You chance would only increase if you were one of a naturally conceived triplet (with at least one fraternal).
doubtful Yes, only fraternal twinning (caused by releasing more than one egg) has a genetic connection, and that connection only holds on the mother's side. So, many twins are born with no family history of twins at all.
No, it has to run on your side, as far as I have read anyway.
I DONT KNOW WHAT THE CHANCES ARE BUT MY SISTER-IN-LAW AND I BOTH HAVE A SET OF FRATERNAL TWIN GIRLS. HERS ARE 10 YEARS OLD AND MINE WILL BE 1 YEAR OLD IN ABOUT 2 MONTHS. IM SURE IT HAPPENS BUT I WOULD IMAGINE ITS NOT COMMON. MY HUSBANDS MOTHER WAS SHOCKED THAT HER DAUGHTER HAD TWINS, AND THEN HER SON HAD THEM. MY HUSBAND AND SISTER IN LAW ARE NOT TWINS. THEY HAVE TWIN AUNTS ON THEIR MOTHERS SIDE OF THE FAMILY, NONE ON THE FATHERS, AND I HAVE SEVERAL TWINS ON MY FATHERS SIDE, BUT NONE AT ALL ON MY MOTHERS. THE GENE IS ALWAYS CARRIED BY THE MOTHER TO DAUGHTER, SO I DONT KNOW JUST COINCIDENCE i GUESS.
The chances of having twins can be influenced by genetics, but it's not guaranteed. In this scenario, with multiple twins in the family, there may be a slightly higher likelihood of having twins due to a genetic predisposition, but it's not definite. Other factors like age, ethnicity, and lifestyle also play a role in the likelihood of having twins.
No, twins can have the same father or different fathers. Fraternal twins are the result of two separate fertilized eggs, each fertilized by a different sperm, while identical twins are the result of a single fertilized egg that splits into two embryos.
Of the factors that influence multiple birth, there is only one that could be identified as genetic or explained by family history: hyper ovulation. Hyper ovulation is the tendency to release multiple eggs during ovulation, increasing the chances of conceiving dizygotic (or fraternal) twins. So, in families where the women have a gene for hyper ovulation, genetics would sufficiently explain an increased presence of fraternal twins. However, only women ovulate. So the connection is only valid on the mother's side of the family. 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.
There are two primary types of twins, Identical and Fraternal. Identical twins occur when the egg splits after fertilization. To date no indication of a genetic link has been found. Anyone has a chance, though small, of having identical twins. Fraternal twins occur when more than one egg is dropped during ovulation. This trait can be inherited from the mother's side of the family. Studies have shown that the chances are also increased by being overweight or older.
Yes, twins have more likelihood of having twins than other people who are not twins. >>> This is only true if it is the female who is a twin. Since twinning is caused by either a) ovulating more than one egg at a time (fraternal twins) or b) having the egg separate completely during mitosis (identical twins), it doesn't make any difference whether or not the male partner is a twin. It all has to do with the ova; therefore, only the female's family history of twins matters.
Fraternal twins are the product of two separate combinations of ovum and sperm at the same time, resulting in genetically different children with a shared womb.Identical twins are the result of one ovum-sperm combination, which then splits into two separate children who are genetically identical.If the two children born from one pregnancy are genetically near 100% identical (with consideration for mutations and genetic alterations after the split or post-natal), they are identical.If the two children have closer to normal sibling genetic similarity (around 50%) but just share a birth time, they are fraternal.Also, identical twins share the same gender. If twins are of different gender, they must be fraternal (though fraternal twins can be same gender as well).
