My Paternal grandfather and his sister were twins. I myself have fraternal twin boys. But none of my 1st cousins, or my sister have twins. I have two cousins who have had 3 single births so far, and my sister has had 2 single births as well. I dont know the chances of them giving birth to twins, but it does seem relatively low.
There is no certainty in these matters, but the fact that your grandmother and great grandmother had it probably increases your chances of getting it too.
What are the chances of your offspring having myopathy if your husband's brother has myopathy?
The mother carries the twin gene and can pass it onto her children. However, only her daughters can give birth to twins. Her sons can inherit the twin gene and pass that onto their daughters, who can give birth to twins. But her sons will only become fathers of twins if their wife has the twin gene. So the chances of having twins if your husband is a twin is not possible unless you have the gene. However, if your grandfather passed the gene to his daughter (your mother) and she passed the gene to you, then, yes you could have twins if your grandfather is a twin.
Here are the variables that increase chances of having twins or multiple babies: 1) You the mom are over 45 2)You live in Massachusetts 3)You take fertility drugs or undergo fertility treatments 4)You, your mother, or her mother is a fraternal twin. Skips generations 5)You already had fraternal twins 6)You are Nigerian 7)You are tall or overweight. Here are the variables that decrease chances of having twins or multiple babies: 1)You are Hispanic or Asian 2)You are under 25 3)You live in Hawaii If you are looking for statistics for identical multiple births (instead of fraternal), then the chances are very much less likely than fraternal twins. ~The chances of having triplets or more is 1 in 8100 and odds having quadruplets are 1 in 729,000
Better then those that have no genetic leanings in that direction.
It is the same for any other pregnancy. Abortion does not change the randomness of identical twins or the familiar tendency to have fraternal twins.
Tanner Chance
These chances are very unlikely. Once you have one set of twins, your uterus is so small that it is small enough for only one child. if you have a set of fraternal twins your chances of having a set again are high, i don't think uterus size comes into it. Fraternal twins are the result of 2 separate eggs being released (multi ovulation) and being fertilised by 2 separate sperm, fraternal twins run in familys but anyone can have them and the older you get the more likely you are to have a set of fraternals. Identical twins are the result of one fertilised egg splitting in 2 and this is completely random, identicals don't run in families
its not likely that you will have twins then... normally you will not have a chance of having twins unless your mother side of the family has a history of twins it matter if you dads side does or not and also if you are over the age of 35 years old. Most likely if your siblings are twins the there is a possibility that they them selves or their children will have twins..
The probability is the same as if you had no history of twins in your family. There is no genetic component with identical twins, it is just something that happens. Fraternal twins occur if a mother "drops" two eggs in one month. Your father being a fraternal twin does not make you "drop" more than one egg in a month and so does not increase your chances of having twins. Your maternal grandfather being a fraternal twin did not effect your mother's ability to drop more than one egg and so did not effect your ability to "drop" more than one egg and so does not increase your ability to have twins.
DNA chances are high because it is written in their chromatic genes..however depewnding on their partners they can have jsut one..it all depends on luck and biology..a personal study of the genes i mean twin could say alot of who could receive what
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.
