Angle estimation without any calibration

What will happen to AQ if without any calibration, I mean no temperature compensation and magnetic inclination.

1.the gyro bias can be estimated by acc realtime?

2.the acc bias can be estimated by GPS if the AQ_YAW isn't real because of no magnetic inclination ?
The badly intial AQ_YAW by magnetic would affect the acc bias estimation, thus affet the angle estimation ?
