Could PLL successfully lock a signal which is not 50%duty cycle?

I‘m learning Analog integerated circuit. Just readed the PLL chapter.
Since a PLL can perfect trace the phase and frequency of input signal, whatif it's a signal with perfect periodicity but do not have a 50% duty cycle(let's say 30%), will the PLL successfully lock and trace the input ?

Generally yes. With some phase detector types, the gain may be affected.
