Now, a few weeks ago, my mom went to see if she would be able to give blood. There are a couple reasons why she wouldn't be able to, they're still figuring out if she's eligible or not. But they tested her blood type while she was there, and discovered she was AB (I'm not sure if it was RH- or RH+). She told me this whenever she got home that day, because thats the rarest type..
In my bit of research today after I found out my blood type, I came across some stuff on the genetics of blood types.. what blood types you could potentially inherit based on both your parents blood types. I have no idea what type my dad is, but I know my mom is AB.. supposedly, anyways. The info that I found today (on more than one website) said that if either parent was blood type AB, it was impossible for their child to be type O.
Now, think about this. I'm definately blood type O. My mom has been told she's type AB.
My question here isn't about finding out you're adopted, or parent infidelity, or any of that stuff, because it seems pretty unlikely that thats what happened here. Instead, I was wondering if anyone here actually knew anything about genetics, and if my information is correct.
The other thing I was wondering was the chances of an on-the-spot blood type test being incorrect. This seems like the most likely possibility, but I'm wondering what the chances are. The test was done by someone from Canadian Blood Services, and apparently she was pretty excited when she had her first AB person of the day..
Anyways.. what I'd like to know:
-Some stuff on blood type genetics.. from a person, not a website :\
-Chances of that test being wrong
Thanks to anyone that might be able to help XD Also, I'm not sure if this is in the right place or not. Move it if its not..
