Oh yes, we have most certainly been able identify which traits come from which parent, more than once we've had a professional point out an issue and our response has been "That's not normal? Huh. I/We/He/She do/es that."
Some issues we've just accepted the explanation of long standing traits (ie DH using only one eye to read columns of numbers because his eyes don't pair well). Other issues we have pursed professional assessment as adults, and found it's not an uncommon story to visit a relevant specialist saying "My child was just diagnosed with X, and I think I might have that too."
