I typed "you have your mother's forehead ridges" and my answer wasn't accepted. The correct one shown was "You have your mother's ridges." if I'm understanding the connotation correctly the word /vIlHom/ specifically indicates forehead ridges, not any other kind. I double-checked in boQwI' (my usual trusted resource when I don't feel like doing a ton of internet research, which is always) and its exact translation is "forehead ridges."
EDIT 1 - second time around I tried "your ridges resemble your mother's" just for grins, also not accepted. pretty sure I've seen "vavlI' mInDu' rur mInDu'lIj" accept "your eyes resemble your father's" so it should have worked
(EDIT 1.5 - can confirm, just got the vavlI' mInDu' question again)
