Not in my opinion, todays kids do not have the ‘unique features’ related to heritage kids in the past held, back in the 70s, you could easily look around a high school and tell who had german parents, who had italian parents, even european to a certain degree, traits like large noses, ears, etc are not nearly as common as in the past.
I think this is due to people getting further and further away from their ancestors, back in the days, italians would only marry other italians, germans would only marry germans, starting in the mid 70s people got away from this, people married people from other descents, their kids did the same thing, most people have no idea where they are from today, its a large mixture of nationalities, they have been so ‘intermingled’ over the past generations, kids are looking more ‘generic’, not having those common traits that usually led to one being ugly.
Thats a good thing actually, its what the US was meant to be, a melting pot, people dont really care where your family originated anymore, it doesnt factor in when people start dating, in fact, id say its impossible to tell if a kid today has Italian, German, etc. lineage.
