Can I tell from my traits if it is possible my dads not really my dad?

I am 19 years old, and I just found out that my mother may have cheated on my father about 19- 20 years ago.. right around the time I was conceived.. There is grandma and grandpa which are my dads parents.. I look more like grandma more then I do the rest of my family, and I do not look like grandpa at all. and the only reason I resemble my dad is because of his mothers features that he has as well.. BUT my grandma had another son.. with a different man.. and i have been lead to believe that my mom cheated on my dad with his brother... Now my dad is a little over 3/4 Cherokee Indian.. He has black hair.. a darker skin tone, brown eyes, and the long face.. his BROTHER.. from a different father.. has blond hair.. a lighter skin tone, blue eyes, and a round face.. my mother has brown hair.. very pale skin tone.. and blue eyes.. with a round face.. I have light brown hair.. blue eyes.. very pale skin and a round face.. i have looked at the different dominant and recessive genes.. and i have almost all recessive genes.. so wouldn't it be more likely to have ALL recessive genes if BOTH of my parents did as well?? is it possible that my mom has been lying all of these years? and that my uncle is really my father?? should i tell my dad and maybe have a test done??

Dear Sue1991

Do you really want to stir something up like that?  Does your mother love you?  Does your father love you?  Do your grandparents love you?  If so, then you have more than many people dream of having--you have a family who loves you.

Many children are adopted and therefore, do not resemble any family member.  And yet, they love the parents who raise them more than any "real" parent could ever replace.

WHY delve into something that will only hurt everyobody's feelings?

If you really want to know that much, then take your mother aside in private sometime and try explain to HER how you are feeling.  Ask her in a very sincere way and don't make yourself sound like a teen-aged-smart-alec mouth (I'm not saying that you are).  If she knows that you are sincere and that it really comes from your heart and not just a smart mouth, she will probably be very honest with you.

After that, be thankful that you have a family who loves you and LET IT GO.

There are too many other things in your life that will be more important.

If someday, in the future, you were to have a child with a medical issue, then and only then would there be any real reason to ask.  Otherwise, what purpose would it really serve?

Well.. thank you for you input.. very much appreciated.. except.. the reason I do ask is.. because not only is my father unnecessarily controlling and inconsiderate.. not to mention the years of mental abuse.. which just so happens must be a genetic thing with his family because they are all very controlling and inconsiderate.. ha.. but this side of my family.. if it even is my family, does have a genetic problem. Colon Cancer runs in his family, I've been more fortunate then ALL of my other cousins to go this long with no problems, however knowing if he is my biological father or not will have a major roll in the well being of my future children.
