DEAR ABBY: We have been learning about genetics in my biology class and how you have to get two recessive genes from your parents to have the recessive trait, like red hair. I thought it was cool, so I tried to figure out which traits I got from my parents.
Now I am freaked out because there were several traits I have that I could not have gotten from them! At least one of my parents must have been someone else. I asked my teacher without being specific, and she said I was right. Now I don't know what to do. I wonder if I came from an affair that maybe my dad doesn't know about. Do you think I should ask? -- LEARNED TOO MUCH IN PORTLAND, ORE.
DEAR LEARNED TOO MUCH: Yes, I do. But the people you should talk to are your parents, to get the full history on family traits of relatives from other generations you may not know about.
