How can a child get blood type o?

Answer 1

They don't actually get the blood type, they are just born with it. The basically gain the blood type their mother has because they basically use the same blood. They can also get blood transfusions or the blood and bone marrow has mutated so that they can no longer produce A and B antibodies.

Answer 2

Yes, it is possible.

and this will happen of both parent blood types with different alleles for each, and they will look like this for both :

IBi X IBi

so they will have kids with Type blood O, in a percent with 25%.

Answer 3

We are looking for the possible blood types of the PARENTS.

Available information:

• Baby type A -- can be AA or AO

Baby receives one gene from each parent:

[1] At least one parent has to provide the A gene

• Mama AA or AO and Papa AA or AO = AA, AO or OO baby
• Mama AA or AO and Papa BB or BO = AB, AO, OO or BO baby
• Mama AA or AO and Papa AB = AA, AB, AO, BO baby
• Mama AA or AO and Papa OO = AO baby

[2] Garantee of an AA or AO baby:

• Mama AA and Papa AA = AA baby
• Mama AA and Papa OO = AO baby
• Mama AA and Papa AO = AA or AO baby
• Mama AO and Papa AO = AA or AO or OO

As long as one parent is providing the A gene, the other parent can be any

blood type, but there is only the possibility of a Type A baby.

If both parents are Type A, then there is only that slight chance that the baby will be Type O.

No
