Answers:
Well your parents must be Heterozygous
as in:
your dad is A+O+
your mom is A+O+

therefore, the gametes that joined to form YOUR zygote, had O+ and O+!.!.!. therefore => u r: O+O+ :)Www@Answer-Health@Com

Oh my god, YOU'RE ADOPTED!!

Just kidding!. Everyone has two sets of genes which code for evrything in our bodies,

In blood groups, A and B are codominant and O is recessive to both!. Both your parents will be genotype AO meaning that they have one copy of A each and one copy of O each!. It just happens than when these were 'shared out', you got an O from each parent and your sister got either an A from both or an A from one and an O from the other!.Www@Answer-Health@Com

You have the same blood group as me, thats the most common!.
My mum was A negative (-) which is the rarest of all and my dad was O positive (+)!.
It stood to reason that all of us kids would be the most common!.
With you I am sure its just nature playing around but you are the luckiest actually as your blood will mix with most partners in baby making!.
My mum and dad had a real bad time!.
