Would Shedinja and Ninjask both be shiny if Nincada is also a shiny?

Question

I seriously wonder about it.

I’m kinda amazed this hasn’t been asked already.

Answer 1

Shedinja inherits the same game of origin, personality value, IVs, EVs, OT, Trainer ID number and Secret ID number, and met location as the Nincada that shed it. It also inherits the Pokérus if the Nincada had it. Among other things, due to keeping the same game of origin, personality value, and Trainer and Secret ID numbers, Shedinja will be Shiny if and only if the Nincada was Shiny.
