biologically speaking, boys tend to take after their mothers in terms of what phenotypes passed down, so you have more than enough to go off of when designing the triplets as adults.
True true. But out of 3 boys chances are one of them would have at least some features from the biological dad. For example, I hc Huey as being a little buffer than his brothers later on so maybe their dad was a bit buff as well. Like what about height? Cause the McDuck/Duck side aren't drastically tall so how would that interact with other height types. Also the 'hair' what color did he have? What about eyes? And so on.
Long story short I'm just a sucker for genetics (it's my favorite part of biology) :)
