Yes, ugliness is a sign of poor genetic quality which all Humans find biologically unattractive. But it isn't an insurmountable disadvantage. People are more compatible with differing genetics as well, so it is possible to be found ugly by some and attractive by others.
An extreme example would be siblings, most of the world could think a girl is hot, but her brother probably doesn't find her attractive at all. That's because the two are so genetically similar, they most likely don't find each other attractive.0
