Does a baby always receive it's father's blood type?

Question

I've been told by several people that children all receive their father's blood type. Yet I have my mother's blood type and not my fathers. And I can't find this to be true anywhere I look on the internet. Am I looking in the wrong place? Someone please help me figure this thing out!!

Answer 1

You don't receive your father's blood type. Your blood type results from a combination of components from both parents. Here's how it works:
1. each person has two alleles of the ABO gene, which are either A, B, or neither (O). For example, my mother might have B and B, and my father has O and A.
2. you randomly inherit one from your mother and one from your father. So I may receive B from my mother, and A from my father.
3. if you get AA or AO, you are type A. If you get BB or BO, you are type B. If you have OO, you are type O. And if you have AB, then you are type AB. In my example, I would be type AB, which is neither my mother's (B) or my father's (A) blood type.

In addition, a different gene, the Rh gene, can also be involved. For this one, you are Rh+ if you have at least one functioning copy, and Rh- if both copies are nonfunctioning. This is only important in blood transfusions, where as ABO typing is important in both blood transfusion and organ transplantation.

Answer 2

No, the baby does not always get the father's blood type. It's complex, but it can even have a type neither parent has (such as an A parent and a B parent can have an O child).

If you had genetic testing, not just blood-type testing, you can estimate the chances of the child's getting certain blood types, but ABO typing doesn't go by getting the type from one parent or the other.

If you get a biology book and look up phenotypes, genotypes and genetic statistics, it will explain this.

Answer 3

Everyone has two chromosomes that carry the blood type. So, a person who is type A could either be type AA or AO. B could be BB or BO. AB is always AB and O is always OO. (there is no "type O" "O" just means no blood type), So if you have

One parent A and one parent B, if they are
AA and BB child would be AB
AO and BO child could be A, B, AB, or O
AA and BO child could be A, AB, or O
AO and BB child could be B, AB, or O

One parent A and one parent O, if they are
AA and OO child would be A
AO and OO child could be A or O

And so forth. You can't really tell if you are genetically AA or AO if you have type A blood, without an expensive genetic test, but sometimes you can back-track, for instance if someone with A blood type and someone with O blood type had a Type O child, obviously the parent was AO, not AA.

Clear as mud?

Answer 4

A baby can get either parents blood type. There is not a "set rule" that the baby will get a father or mothers blood type. I have my dads and my sister has my moms.

Answer 5

It used to be a belief in the past that all children would get the father's blood group. This is also why blood tests were done to check for paternity. I think it's still true that most babies will receive their fathers's group but certainly not all.

Answer 6

really its all about who dominats more. I have my mothers blood type, which is great, cause my fathers is very rare. So if i ever need a blood transfusion, (lets hope thsi does not happen) i can always turn to my mother. My partner has his fathes and so does my sister. so there is no true basis on how to predict which blood type a child will get.

Answer 7

No that is an old myth back in the 'bad ol' days' when women were just considered receptacles for the man's "seed"

Answer 8

No it depends on both your blood types. It could be possible that the rh factor an everything is deifferent. My father has A positive and i am o positive so that's a no

Answer 9

No babies do not always have their father's blood type.

Answer 10

No the baby has it's own unique blood type.
