Yes.
If both parents have type A blood then the baby should have type A blood. or type O blood
blood group "A" or "O".
Yes, you can have a sister with blood type O and you can be blood type B. This can happen if you have one parent with type AB or B blood, and other parent with type O or B blood.
If both of your parents have Type A blood, the blood of you and your siblings can be A or O.
If both parents have a positive blood type, the chances of their child inheriting a positive blood type are 100.
If both parents have blood type O, then the baby's blood type will also be O. Blood type O is recessive, so both parents must have two O alleles to pass on an O blood type to their child.
If both parents have O blood type, the chances of their child also having O blood type is 100.
If both parents are blood type A, they can each carry a recessive gene for blood type O. When these recessive genes are passed on to the child from both parents, the child will have blood type O. This is a result of both parents being carriers for the O blood type gene.
Only if it was adopted...the only options for that child's blood type would be A or O if the biological parents are both Type A.
No. Often a child can have a completely different blood type from their parents or even the same. It really depends on their genetics.Some combinations of parents are unable to get children with certain blood types - assuming no mutations occur.Regarding the AB0-system:If both parents have blood type 0, all their children will have blood type 0.If both parents have blood type A, no children will have blood type B or AB.If both parents have blood type B, no children will have blood type A or AB.If both parents have blood type AB, no children will have blood type 0.Of course you can be more specific if you know the parents' genes.
yes
impossible.
