Will you have twins since your grandmother was a twin?

Having a twin sibling or not is dependent on genetic and biological factors, not directly inherited from grandparents. The chances of having twins are influenced by genetic predispositions but do not solely rely on a grandparent's history of being a twin. While genetic predisposition can sometimes increase the likelihood of having twins, the occurrence of twins in the following generation is not strictly related to a grandparent's twin status.
