Look Closely At This Family Photo. The Chance Of This Happening Is One In A BILLION…

A lot of people believe that having twins is determined by genetics and this is true to some extent, but in reality, the chance of a woman giving birth to twins is fairly unpredictable. People often might expect multiples, but there's never a guarantee — and we all know babies have a habit of surprising us from time to time!

As you've seen recently with twins like these one-in-a-million sistersanything is possible.

The chances of a woman becoming pregnant with identical twins is less than 1%…and the chance of an identical twin having identical twins herself is virtually unheard of at a microscopic 0.02%.

You can imagine the shock when Christian Fernandez, who has an identical twin named Jenn, became pregnant with twins. However, Christian's daughters turned out to be just the beginning. Nine months later, her twin sister Jenn became pregnant…

With identical twin boys! As far as Christian and Jenn know, there are no other documented cases of identical twins both having their own set of identical twin babies.
