cockatiel mutation

I have a male white face pied cockatiel and a female cinnamon pied pearl cockatiel and was wondering what the mutations of their chicks will be.

I got a cockatiel 2 weeks ago, I was told that it is a male cockatiel but I do not know the mutation of it. And I am not sure about it being male either. It has got a bit of an orange-ish cheek patch, and it doesnt make much noise, but that might be due to it being only 6 months old or just not...
