"Jsi po otci nebo po matce?"

Translation: Do you take after your father or after your mother?

[JohnBraga1]

how would you translate "Are you for father?" meaning "Are you on father's side?"? Do you not use po?

[JanLyko]

We do not. I am afraid that the only possible forms are literal "Jsi na otcově straně?" and "Straníš otci?"

[JohnBraga1]

děkuji!
