Blood type not the same with Father...

Published

Do children always have to have the blood of their father? If your blood is not the same with your father, does this mean you're not his child?

Nope.

Google "blood type genetics" and you'll find a plethora of information.

You've been watching too many soap operas ;) Because only in soaps is blood type the guaranteed indicator of paternity (or lack thereof).

Remember that the child gets one gene from each parent, and that the O gene is recessive so you'd need two of them to be a type O. So someone with AO or AA is type A. If the parents are both AO (and they may know they're A, but not AO), the kid can be O and still be their kid because he got an O from each parent.

Blood type is very unreliable as a means of confirming or denying paternity. True, there are a few cases where it could rule out a father...for example, if the parents are both Type O but the baby is Type B, then someone's got some explaining to do ?

But there are so many other combinations possible where the father's type doesn't have to match the kid's though they are definitely parent-child. Another example: if dad is AB and mom is BO, then the kid can be AO (A), BO or BB (B) or AB (AB).

Last, blood types can not confirm paternity. The kid's blood type may match the father's (or be a possible combination of the parents'), but that doesn't mean that he really is the father.

It's all basic ABO info and is in your med-surg text. Rh factor works along the same guidelines.

Hope this helps!

Offspring may have the same, or different blood type than their father.

Offspring may have the same, or different blood type than their mother.

It all depends on which genes they happened to pick up.

Nope...my dad is A, I've got my mom's O negative...which for me basically means I get an on the dot phone call from the red cross every two months!

I am O negative as well, I get that same call!

My parents are both O positive, my brother is O positive, my twin sis and I are both O neg. We got the recessive gene for negative blood from both our parents. Funny how things work sometimes!

Blood type means nothing. DNA is 99.4% accurate.

My blood type is O+, my son's is B+, his father is AB- When our son was born in Boston, MA 1980, we were told by the nurse at the hospital that the father could deny paternity and refuse to sign the birth certificate because of the difference in blood types. He accepted the suggestion.

My family has 'em all. A, B, AB and O. My daughter is O- and has yet to be able to donate. I swear the last time she tried, the lady who gave her the news that she didn't qualify (my daughter only weighs in at 104lbs) had tears in her eyes. So did my daughter, she wanted to donate.

It's funny, she eats nearly everything in site but she is just so active. She's had ADHD all her life so when she gets restless, she's learned to let go off the excess energy by dancing around. I so wish I could bottle that girls energy! And she LOVES Five Guys!
