frank has type A blood (AA or AO) and margarita has type B (BB or BO) blood. They have a new baby. Vinnie, with type O blood. Is this possible or should frank accuse margarita of cheating?

It is technically possible, if and only if, both parents have AO and BO blood.

Explanation:

the only way (most of the time) a child can get O blood is if both genes accepted by the parents are O.  That would mean both parents would have to have O recessive genes.

i think its control and coordinate because im pretty sure thats what tissue does and the joints are what control movement and then your skeletal/ bones provides portection. hope that .
