My cousin just found out she's expecting identical twins! Our family is VERY excited!

Our great-grandmother is a twin (I just found this out, and i'm not sure if she was an identical twin, or fraternal). I read online that it's fraternal twins, not identical, that are hereditary.

Does anyone know if this is true or not?

  • Fraternal twins CAN be hereditary, on the mother's side as they result from two eggs being released at once. Identical twins are the result of a single egg/sperm combo splitting into two separate babies, this is not known to be hereditary, just a really nice bonus!

    I have twins on the maternal side of my family, most are fraternal; my twins were identical, so it was just a fluke. Your chances of having twins increases a bit with age as well as with having more kids.
