Nope
it doesnt!
i was adopted. I did ask myself the same question. the answer is NO!
I have nothing in common with my mom... I never had a dad. I do things totally different from everyone in my clan... I act like my dad *supposevly* ... My mom kinda knew someone who was in labor around the same time when my bio was having me.. my mom was worried that iw ould turn up like my bio.. I am nothing like her. my mom's sisters'kids are a lot alike even though they dont have much of a contact among them. My 2 cousins are doctors, my cousin brother is an ex engeneer currently a farmer. I am an enterpreneour, i am the most progressive person in the entire clan. So I do not know what to tell you.
