What are the determining factors in your blood type? Is it hereditary?!
Question: My mother, sister and I all have B- type blood and so does my son. My husband has AB+ and my daughter has A+. Just curious. Not many people know their blood type. Why?
Answers: My mother, sister and I all have B- type blood and so does my son. My husband has AB+ and my daughter has A+. Just curious. Not many people know their blood type. Why?
Yes, it's hereditary. I once studied this stuff so will try to explain it (but I might not be 100% right, please look it up in a biology book to make sure!).
Imagine it like this: everyone has the base group, which is O.
To be A, you have to have an A attached onto the O.
To be B, you have to have a B attached onto the O.
To be AB, both an A and a B group will be attached to the O.
That's why everyone can receive O blood, because we all have it as part of our group (although, ideally, we'd prefer a perfect match, A for A, B for B, AB for AB, but in a life-threatening situation O is the next best thing until they type you exactly (and your Rhesus group too)).
A groups can also receive A blood, but not B.
B groups can also receive B blood, but not A.
This is because the A or B component will attack the other and destroy it (it's a bit like having an organ transplanted into your body, your body sees it as an invader and attacks it, that's why you have to have immunosuppressant drugs).
AB group can receive from anyone- lucky them!!
O people can give to everyone, which is lovely for the rest of us however they can only receive from other O people- not so good for them!
Fortunately, about 40% of the world's population are O types.
Which is good for everybody :o)
**The negative/positive aspects also affect things.
Negative types can only receive from negative types, but positive types can receive from both negative AND positive. This means, at one end of the spectrum, if you are AB+ you can have blood from anyone, however if you are O- you can only receive from another O- . All the other groups are somewhere in between**
HOPE THAT HELPED AND WASN'T CONFUSING!
P.S. You might think that this is a load of rubbish (I used to) but read the book "Eating right for your type"....you'll be surprised.
P.P.S. It's amazing how much stuff comes back to you, once you start thinking about it...I just hope I haven't got it all wrong!
im not sure
Yes it is heredity
hereditary but you must look at your grandparents too./

blood type is hereditary.
It's purely hereditary. You have a "B" and no "Rh" (that's what the minus means.) Your husband has an "A" a "B" and an "Rh" (the + or - is whether you have the Rh.)
I'm pretty sure it depends on ur parents and wat's dominant or recessice.
i'm assuming many people do not know heir blood type maybe because it isn't brought up tht oftn unless for possibly health reasons
It is heredity. You can have A, B, AB, or O. There is one gene pair for the blood type from each parent and it carries either A or B. Type O is the lack of A or B.
I certainly never understood why most people have no clue as to their blood type. We do in our family. I am AB negative and my husband is 0 positive. So, our children could only be B plus or minus, or A plus or minus. Our sons are A pos. and B positive. Since I had my children before Rhogam was used extensively, it was important to know my blood type. Yes, your determining factor is completely hereditary.
it depends - is your husband the father ?
yes it is genetic but blood type is co-dominant. The plus or minus is related to Rh factor and is more complicated but also inherited. For example, if your husband is AB he could've given either a dominant A or a dominant B to your daughter. Since you
have a B blood type that means you are either BB or Bb, but since your daughter is A, you must be Bb and she received the recessive b allele from you and the dominant A allele from her father, so her blood type is Ab, but because the A is dominant and the b is recessive, we just say A.
its a simple punit square. your blood type is made of a combo of alleles, A B and O. draw a 2 by two box (four sections) put your alleles (B and O) on the top of the box and put your Husbands (a b) down the side of the box. the resulting combos are the possiblities for your children. the signs add complication to the process but can also be found this way. its simple high school biology
About 85% of the world is Rh positive. You, your mother and your sister are all rare. It is hereditary and if your father was positive then you inherited the Rh factor from only your mother and your children could be either - or + since your husband is positive.
Knowing your blood type is really only important if you're preparing to receive a transfusion.
Your blood type is determined by your genotype. That is, specific genes in your DNA will enable you to produce different antibodies, resulting in a specific blood type.
Children inherit genes from their parents, so blood type depends on parents.
Modern blood typing is much more complicated than the familiar A, B, AB, & O system.
