Zee Aviary Cockatiel Genetic Calculator(Nymphicus hollandicus)
Pick what each parent visually shows or is known to carry, and see the probability breakdown for their offspring — including the real sex-linked crossover behaviour between yellow-cheek, cinnamon, lutino and pearl.
Sex-linked mutations
Cinnamon, pearl and lutino are carried on the Z chromosome — hens can't be split for these, only cocks can.

This tool models the consensus breeder/genetics-community understanding of these mutations, not a peer-reviewed study. Gold Cheek's inheritance mode isn't confirmed by any source we could find and is modeled as a best guess.
