If twins run your family you have a higher chance of having twins yourself but it doesn't necessarily mean you will for sure have twins
Twins are more prevelent if there is a genetic history of them, but no, it does not mean you WILL have twins. Your chances are simply better.
Higher chance, but not a definite.
Is she a fraternal twin or an identical twin? I have heard that everybody has the same odds for identical twins because its an embryo that splits into two babies. And then people with fraternal twins in their maternal family side have an increased chance for having fraternal twins because the ability to release two eggs to be fertilized is a genetic trait passed from mother to daughter. IDK how much scientific evidence there is to support this its just something I read.
