#38 I wish I could like your comment twice. :)

For those of you saying that there's nothing wrong with being adopted, you're right. But I think OP isn't upset that he/she is adopted, rather they are upset that they did not know until now. That's a pretty big thing to take in. Of course they'll probably get over the most of it after a while, but there are so many questions to be answered. It's understandable that OP is a bit shaken up or upset. I hope everything is sorted out soon.

I almost failed a biology assignment about family traits in my first year of college. I chose to document the eye color of my family. Both my mom and dad (and both sets of grandparents) have blue eyes but my brother and I have brown. I had to bring in proof that my dad was really my dad before the teacher believed that I understood the assignment.

I'm adopted and I find this offensive. Don't look at it as a negative, look at it as a positive! You are a very special and loved gift that your adoptive parents wanted. How is that a bad thing?!

It's probably a good thing in the long run, you were chosen and not the subject of resentment.

There are lots of genetic traits that can tell you if you are adopted, it doesn't have to be the eye color. One is if your body can produce that special urine smell after eating asparagus, another if you're lactose intolerant, if you're a bleeder or colorblind, others are hair, skin or eye color. Most of these traits are dependent on several genes, not a single one. Since every human has every gene twice (since they have all chromosomes twice, except for X and Y in men), one from the father and one from the mother (who gave you a copy of one of their two each, which were handed down to them by their moms and dads), deductions can be made by observation. Since not all traits are simple to deduce, only certain traits can be used to see from which parent you got them or if you're adopted. Imagine, some genetic traits are to be found only in the mitochondrial DNA, which only can be passed on by women with their ovum. I can imagine that a biology teacher would know for which sure-fire traits students should look for in their parents. Unfortunately, adoption or infidelity can be found out that way. Apart from that, it's all science and there's not a shred of fate or luck in it. Genetics is hugely fascinating, and were it not for companies like Monsanto, genetic sciences could have a good public image. I also wanted to add that you can't "believe" or "not believe" in evolution. It's a fact, as well proven as gravity. You can't "not believe" in gravity either. Well, you can try, but it won't help you when you step out the window. The scientific term "theory" is something entirely different than the vernacular term "theory", which means "wild idea". Also, mutations don't really happen on a level so complicated they give you completely new traits like in X-Men. About 99,9999% of mutations end in cancer or programmed cell death.

What the **** is wrong with being adopted?

How did you find that out?
