Find out if the mailman has the same blood type as you. Simple answer, but your mom would have some explaining to do. Or you were adopted

Adoption is 4/5 mutation is 2/5 and illegetement child 1/500 those are the odds seeming neither of your parents have B blood type you could be adopted and thats fine my best friend is adopted do you have any second languages?Try reading something in a diffrent language then english if you understand it then that could also mean your from the place that people speak that language if you have never taken spanish class try to read this Hola mi amigo como estas? now what does it mean? and, another possiblity that you did not list is affair? i know thats the last thing u want to know that your mom cheated on your father or had sex before then and had not fertilized yet.it is possible in alot of cases such as this its a big possiblity aswell as adoption.so try to do some research talk to your parents tell them that you found out your a B blood type and ask them and if they dont feel like talking about it infront of the other spouse take them both seperatley and record the results in a nootbook cause they most likley have alot of stuff to tell you.Before this takes up the whole page better be saying goodbye.try to read through other comments and see what other people say. alot of people are gonna say to talk to them.Goodbye and godbless

It actually is possible. I am B+ and both of my parents are a different blood type then me and I am definitely both of my parents biological child. Here is how this is possible: This is for blood type: PARENTS' BLOOD TYPES POSSIBLE CHILD NOT POSSIBLE CHILD A and A A, O B, AB A and B A, B, AB, O no A and AB A, B, AB O A and O A, O B, AB B and B B, O A, AB B and AB A, B, AB O B and O B, O A, AB AB and AB A, B, AB O AB and O A, B AB, O O and O O A, B, AB And this is for Rh status (what makes it positive of negative): Mother's Group Father's Group Rh + Rh- Rh + Rh + Rh +, Rh - Rh - Rh +, Rh - Rh - I hope this helped you.

Okay first of all **** you for thinking "FML" over being adopted. If you are adopted at least someone cared about you enough not to leave you for dead or abort you. Be ******* grateful. I always believe parents should tell their kids if they're adopted from the moment they can understand the concept--I've always known I'm adopted and it's not a difficult concept to deal with. But it's not something to freak out over. So, **** you. I realize you also said "mutant" and "illegitimate" but those are not as likely as adoption. Secondly, you're an idiot. Read the post above me.

Also possible if you were given a total blood transfusion after birth.

in a way, its kinda funny at the thought of u possibly being a mutant. but all in all, that blows.

have you asked the mailman what type he has?

And it is possible that you may be your parent's children. There's something called a chimera, and that's where you're made up of cells from your body and someone else's. This happens plenty of times, especially if you have an older sibling. So that means that while genetically you may not be your parent's child, you may actually be their child anyways. It would be interesting to see if you were your aunt's or uncle's child.

They still love you.
