No way...
If both parents have blood group A, their children can have blood groups A or O. This is because the A blood group can be either AA (homozygous) or AO (heterozygous). If both parents are AA, all children will be A. If both are AO, children could be A or O. If one is AA and the other AO, children could also be A or O.
You could have several children with different blood types. you get your blood type from either parents or even grand parents.
both parents could be A heterozygous or one A heterozygous and the other O
No - if both parents have blood type O, then the only possibility for their children is also blood type O. If they are both heterozygous for Rh (+/-) then they could have either + or - children. If either of them are homozygous (Rh+Rh+) then all the children will be +.
No, unless they adopt.
For A+ and O- parents, the child can be either A or O, and either + or -. They are slightly more likely to be O+ than any other.
You don't get just one or the other. For example: If your blood type is AB, either of your parents could have A, B, or AB. Another example: I have O and my husband has O. All of our children will have O, because O doesn't combine with A or B.
If both parents are O negative and O positive, their children may inherit various blood types depending on their parents' genotype. However, all children will carry at least one O antigen in their blood type. The parents could have children with blood types O negative, O positive, A negative, A positive, B negative, B positive, AB negative, or AB positive.
The offspring could have either B or O blood type. They could also inherit the blood type from either sets of grandparents. If one or more grandparents have the blood type A, this could result in AB or A, for example.
Could be anything, we get our blood group from either parents or grandparents.
The children of parents with blood types IAIB and ii could have blood types IAi or IAIB.
