What does tu padres es el de abuela paterna in English?

This phrase is grammatically incorrect in Spanish. It seems to be trying to say "Your parents are your paternal grandmother's..." but it's missing the final part of the sentence.

Here are some possible English translations depending on what the sentence is meant to convey:

* "Your parents are your paternal grandmother's children." (This is the most likely meaning)

* "Your parents are your paternal grandmother's..." (followed by something else, like "siblings" or "relatives")

If you can provide more context, I can give you a more accurate translation.
