[General Sci-Fi] What happens if you get the female version of you from another dimension pregnant?

Would the baby come out as a clone of the mother or father? Or would it be more like incest, resulting in a deformation of the baby?

For there to be a female version of you from another dimension, it requires that either that you have different genes or that somehow biology works differently.

Ignoring those concerns, the most likely outcome is high likelihood of problematic genes.  Our eggs / sperm don't always contain the same genes as each other (or a specific half), so there's no reason to expect that the child would get complementary halves from the parents.

There are some stories that deal with a similar issue -- notably, [](#s "Predestination") which is based off of [](#s "All You Zombies") -- but in this case, they're about [](#s "time travel and impregnating yourself") which results in [](#s "your own birth").
