A child that has a blood type of A+ means that at least one of the parents was either A or AB.
So, for the child to be type A,
one parent could be AO and the other OO
or
One parent AB and the other parent OO
or
Both parents could be AO.
One allele is taken from each parent. At least one parent must have an A (either A or AB blood types).
The positive part of the A+ is inherited independently of the ABO blood group. So, at least one parent must be Rh+ for the child to be A+.

Nope it means that some trait passed on by the mother and the trait passed on by the father created A+ blood type.

Yes, one parent has to have A+ blood. I take that back. One parent has to have the gene for A+ blood, it does not need to be expressed. I think that it is usually expressed (I think it is dominant) but I don't remember.

the child had to inherit the blood type from a parent, probably the father.
