Blood type Question

[Roenick]

I've looked and can't find an answer...


If two parents are both positive blood types, can they produce a negative blooded baby?

And vice versa... could two negs make a positive baby?

I'm sure the medicos on the board will jump in here, but IIRC, Two parents who are both positive CAN produce a blood type negative child, However, two negatives can not produce a blood type positive child.

I'm calling on memory of 7th grade biology here and a WHOLE LOT more is known now about blood than when I was in the 7th grade (~1954) LOL

However the theory I'm recalling is based on the assumption that each parent contributes to the type of blood of the child (and each of them were contributed to by both of their parents, etc.)

Also, Pos (+) is dominant. Meaning that if that gene is present it will prevail, so if you have two parents who are both positive they COULD both be carriers of the Negative (-) gene == Dad(+/-) & Mom(+/-). Now if each of them happened to pass on their pos. the baby would be Baby(+/+).

Their would be a 3 out of 4 chance the baby would be positive.

Dad(+/-) & Mom(+/-) if their contributions are like this:

1.Dad(+) & Mom(+) = Baby (+/+) (Positive)
2.Dad(-) & Mom(+) = Baby (-/+) (Positive)
3.Dad(+) & Mom(-)= Baby (+/-) (Positive)
4.Dad(-) & Mom(-)= Baby (-/-) (Negative)

Is that still how it works? (Oversimplified, I know.)

Good memory, PatC.

This link has an answer that agrees with what PatC said about two negative parents. http://wiki.answers.com/Q/Can_a_baby_be_born_with_rh_negative_blood_type_if_ the_neither_one_of_the_parents_has_this_type
Do you know your blood type. I find a lot of people don't.

I do! I do! I'm A Neg. Since my boys' daddy was O Pos. There was always a risk factor if there had been a placenta leak from a baby whose blood was Pos. My blood could have created antibodies to fight the "danger" and that would have put the baby at risk.

However, knowing that, I also knew when the doctor came in after my second son was born and proudly announced he was a healthy boy with B Pos blood that they needed to either run that test over or find out whose baby it was for because I KNEW WHO MY BABY'S DADDY WAS and there was no way we had a child with type B blood. At first the doctor thought I was ... well I don't know what he thought but he acted like he was going to ignore me until I got really insistent! Turns out my son had A Pos. blood, and I had an embarrassed doctor.

That Rh factor has subtypes.

I used to know a med tech, and she said if the positive parent contributes a negative that is recessive for him her while showing positive themselves, it can happen if they have a mixed type.

For example, my father was A+ and my mother B- and both my brother and I are B- (I have negative negative subtype) I have a civil defense tag showing the subtypes D-C-) done in 1950 when I was in kindergarten.
here is a link:
A far more useful breakdown involves the Rh (Rhesus disease) factor. If a person has a positive Rh factor, this means that their blood contains a protein that is also found in Rhesus monkeys. Most people (about 85%) have a positive Rh factor, and doctors are trained to monitor closely any woman who is Rh negative and becomes pregnant. The Rh system is actually much more complicated than the ABO system because there are about 30 combinations possible, but for the sake of simplicity, Rh is usually expressed as either positive or negative. The Rh factor, like other antigens, is found on the covering of red blood cells. It's common for a forensic scientist to take the percentage distribution of the Rh component, which is expressed as plus or minus, to present some of the blood groups in terms of odds-ratios:

I think it is very complicated...requiring a specialist.

For example my husband is A+ and I am B- (same as my parents) and our son is AB+

[packy]

I was looking for info about my B+ type and found this that shows how complicated it can be. http://anthro.palomar.edu/vary/vary_3.htm

Thank you, all.


I'm O-
My mom and dad are oposites, luckily I was neg like my mom




I asked because I was sitting here last night with my cousin and she was telling me that it sounded like my grandpa was questioning his sons paternity. My uncle was kidney cancer and needed blood but I'm the only one that could give to him.
She said that he could have just been wrong about what he and my grandma were but we looked and couldn't find a simple answer we understood.

My RH factor is negative.. and it does create problems with pregnancy and blue babies. My two oldest were fine but blood transfusions were done with my youngest. A shot is usually given at birth of first child but I was carrying my second before it was discovered that I was O negative.
Back then (when I was carrying my oldest child) it wasn't requried a blood typing be done when pregnant. :(

Amniocentesis was done during my pregnancy with my third child. Doc used a Big tube and a long small Needle!!! LOL

[Topaz]

I had two RhoGam shots. One after my amniocentesis at 4 mos, and one after delivery.

Type O- is the universal donor...anyone can accept O- blood

Type AB+ is the universal acceptor-- can accept from any donor.
AB is a relatively new blood type, none has been discovered prior to
800 A.D. by genetics researchers checking on old bones etc.

I do recall reading about the additional sub-types, e.g., D, C, etc. When I was studying it, our texts were still addressing only the ABO system. IIRC, what we call O type blood simply referred to blood that did NOT have either the A or B factors.

Roenick, with O Neg. blood, you'd be a handy person to have around in case of an accident. LOL I don't know what type blood your uncle has, but like Topaz pointed out, with O- being a universal donor, it doesn't really matter.

I had the RhoGam shots too, after both deliveries and after my miscarriages. Apparently, I never did get "sensitized" but I don't think I want to have any more babies, thank you very much. :girl_haha:

[Texas53]

I'm O+. I think my blood type is the most common. At least its the type always needed during blood drives. But I can't give anymore since I've BC.

[FLYSODA]

my story of my blood type came a little different to me. from an early age I knew my blood type. 0+. my husbands is B+. My mother was an horrible racist. Jews had B blood. and AB blood. A blood was ok but not good enough. O + was the best best blood for the chosen people. but most black people have o+ blood. when she found out my husband had B blood, she disowned my kids. and never saw them. never knew when I gave birth. and could care less. called me a jew lover. and didn't see much of her after I turned 19. she wrote me out of her will. which I don't really care about. but this woman was insane. who cares what blood type you are unless you need blood. my sister went in for surgery not long ago and had her son give blood before she went in case she needed blood for her surgery. she didn't want a strangers blood in her veins. this is just one of the things my mother brainwashed my siblings with. and out of all my sisters kids, my kids are the most successful. one sisters kids are drugs addicts. ones are losers. one didn't have any to prove a point. and my brother, his youngest son went to prison for 5 dui's. He's out now and working a full time job. doing good. So if marrying a person with B blood means your marrying a jew, then everyone should marry one. He's a good provider, a good husband, forgiving, faithful, takes take of his family. Is an excellent father. and I don't deserve him. but he loves me. and tells me so every day. blood types shouldn't matter when it comes to love.

Fly, the more I hear about your mother the more amazed I am she stayed this side of a padded cell.

You are so incredibly luck to have gotten away from her!

Neither blood types nor race should matter when it comes to love, or anything other than a medical issue. But IIRC, the blood types are slightly racially linked. Too bad for her, but indeed, O is the oldest type, and thus, came from Africa, and those dark skinned people that I doubt she likes. That's why black kids have it, quite predominantly, as well as the rest of us. A and B are later mutations.

Pat, the best thing she ever did for me was drive me to another state, dump me off with my suitcase, give me a dime for the payphone, buy me a paper and drive off. that was good ole mom. she could never kill my spirit.

hey fly... this is the first time i've ever read any of your posts... and now i find myself looking them up to see what else you wrote about. man, what a life you've experienced.... i can relate to a lot of the stuff you talk about... guess i'm just not so bold as to just "put it out there" ya know?? not yet, anyway. keep writing... and i'll keep reading! you have a lot to say!

[RayStar]

Is it important for one to know their blood type and keep handy? I mean like as important as which meds one may be allergic to? Good reading here. I am negative. I know after the birth of my kids I had to have an injection. Now I know what it was. I think back then it was called something like hemoglobin for antibodies. Never thought about race in blood other than sickle cell anemia with black people and something with Jewish Ty-something.
