RF oscillator harmonics varied by the same amount as the fundamental?

I have a crystal oscillator that generates the fundamental frequency and harmonics of this frequency. Suppose the fundamental is 1MHz and the 10th harmonic is 10MHz.

If the oscillator drifts to 1.1MHz will the 10th harmonic drift to 10.1MHz or to 11MHz?

According to my pocket calculator: 1.1*10=11

ok I just wanted to make sure that the harmonics follow a percentage multiplication.
So the FM deviation of a signal that is FM modulated on 1MHz will be greater on 10MHz, i.e a small amount of fm deviation on 1mhz will produce a large amount of fm deviation on 10mhz, right?

About FM, f1 denotes 1, f2 denotes 0, so the base tone (1M) is sin(2*Pi*f1*t+Phi1) or (2*pi*f2*t+Phi2).
If 10M is 10th harmonics of base tone, then deviation of 1M would produce 10 times deviation on 10M.
But if 10M is mixed from 1M and other LO, say 9M, then deviation of 1M would produce same deviation on 10M.

thank you very much
