Sure is possible!!!
I shall explain it for you...
Try this http://www.biology.arizona.edu/Human_Bio/problem_sets/blood_types/inherited.html
If you know genetics...
A blood is possible with 2 genotypes AA and AO
( A is the dominant part, so A will get expressed)
AO (Your Fathers) AO (Your mothers)
A O | A O (they are the gametes)
There are 3 types of children possible > 2 with AO and 1 with AA and 1 with OO
The last one is you! (OO)
I know its very hard to understand!!
But that is the truth....O+ is possible

Yes, everyone carries two sets of genes to determine blood type-- one from their father and one from their mother.
Example:
A mother carries type A+ and O+
A father carries type A+ and O+
The child can either get A+and A+, A= and O+, or O+ and O+
If he get two A's then he's an A.
If he gets two O's then he's an O.
If he gets an A and an O, his blood type will fall to the dominate gene .

Yep sure is! a+ blood is named in science by a capitol I with an a as an exponent. afterwards comes a small i. when you were consieved your mother gave you her i and your father gave you his i instead of their capitol I's with the exponent a's . This made your blood type ii also called type O blood.
I thin Rattler explains it better than I do! YOU GO BUD!
If you dont understand (which you probubly wont cuz I suck at making sense period) then you can just search the net cuz im sure there's some website that can explain it.

Yes it's possible because O is a recessive gene. They both carry the O gene. The only blood type that can't carry the O gene is AB. Blood type A can either be AA or AO. Your parent's are both AO and both gave you the O.

Yes, see the source, A is a dominant gene, so both of your parents were carrrying an O gene which was overriden by the A, but when the two O's were paired (one from each parent) you came out O. + is handled another way.

It deals with genetics. Your mother is A and your father is A. "IA" is a trait for A blood type. "i" is recesive. IA is dominant. I your mother is [IA,i] and your father was [IA,i] this means that they are a blood type of A since that is what is dominant but they are a carrier for the recesive. during reproduction you get half of your mothers DNA and half of your fathers DNA that includes blood type gene. Here is a table to give you a visual...
.......IA / i
IA [IA,IA][IA,i]
-----------------
i [ IA,i ][ i,i ]
On top is your mother and the left is your father. You receved your blood type from the 25% chance of a [ i,i ] which is O blood. I hope you understand.

yes, every person has 2 allels for blood groop. humans have a, b and o. So someone can be aa, ab, ao, bb, bo, oo. so if you are o, then your mom and dad must both be ao. You inherited one o allele from each of them. the + refer to the rh factor. so yes you and your parent both have that.

Yes blood type isnt just paternal it could be from a grand or even great grandparent its all genetics.

yes one of your parents could have had a recessive on their gene (which is an allele that doesnt show up but could show up in their offspring) dont worry. u arent adopted :-)

no it is not possible unless there is a recessive universal gene. The chance is slim but I would ask your parents if there is something you dont know.
