If my father's blood type is AB and my blood type is also AB, what are the possible blood types of my mother?

Question

let's say, I'm really the daughter of my parents.

Answer 1

AB blood group system in Humans is the co dominant type

If Ur fathers blood group is AB X Mothers ?

Ur's is AB

Answers--->
--------------------

1. Father AB X Mother AA ----> Ur's may be AA or AB

2. Father AB X Mother OA (Means A-group) ----> Ur’s AO or BO (means all will be A-group)


3. Father AB X Mother AB ---> Ur’s AA (A-group) or AB (AB-group) or BB (B-group)

4. Father AB X Mother BB ---> Ur’s AB (AB-group) or BB (B-group)

5. Father AB X Mother OB (Means B-group)

---> Ur’s OA (A-group) or AB (AB-group) or BB (B-group) or OB (B-group)

So, Ur mother’s might be case 1 or 3 or 4 or 5 , but not case 2

Answer 2

All the groups except type O
You see she could never be type O because she have to "donate" some genes.
If she is type A then your dad donate the B
If she is type B then your dad donate the A
If she is type AB then your dad donate either the A or the B
Type O does not fit in the scheme because you are AB and O does not have any of these

In other words you actually need to carry out a test to establish the blood group, but from this information you have provided she could be in all the groups except type O. Good luck

Answer 3

I think that your mother would have to be either A, B, or AB like you. I don't think that she could be type O. By the way, AB is considered the universal donor. It is the rarest blood type, I think.

Answer 4

Your mother could be A or B or AB.
If your mother were A, you could have inherited the A gene from your mother and the B gene from your father, making you AB.
If your mother were B, you could have inherited the B gene from your mother and the A gene from your father, making you AB.
If your mother were AB, you could have inherited the A gene from your mother and the B gene from your father or vice-versa.
The only group your mother could not have been is group O.

Answer 5

AB or 0,
A itself is dominant as B is

if you wanna have a more detailed explanation - read a book on genetics

Answer 6

AB is rare, but O is universal. She could be A, B, AB, or O. Unome was incorrect and Sarek was correct.

Answer 7

your mom could have anything. o just means one doesn't have either A or B present. it doesn't mean they have anything additional. so....if you add 1 (AB) plus 0 (o) you get 1, right? AB plus O equals AB.

if your mom had A. it would be AB plus A equals AB.

if she had B. it would be AB plus B equals AB.

if she had AB. it would be AB plus AB equals AB.

Answer 8

O,A, B, or AB
the person above is wrong, AB is not universal donor. O is universal donor, AB is universal recipient.

Answer 9

Your mother could have any of these phenotypes:
A
B
AB
