In order for Smeargle breeding to work, does Smeargle have to be male?

Question

Or is this situation similar to the Ditto situation where it can breed with any breedable Pokemon without fail? I wanted to know the basics before I started breeding moves onto other Pokemon.

Answer 1

At first, what are you meaning by Smeargle breeding? If you are meaning passing down moves, then no. Generation 6 onward, both male and female can pass down moves.
If you are Meaning passing down moves on another Pokemon, then yes. Because if you breed with a female smeargle, then smeargle will hatch smeargle.

Answer 2

It's not like Smeargle is so difficult to breed, it's just like any other Pokemon. There's nothing special about it, just pair it with something else in the Field Egg-Group and you'll be fine.
If you want your offspring to be a Smeargle then you'll either need to use a Ditto or catch a female Smeargle, because hatched Pokemon will always be the species of the mother.
I imagine your confusion might come from how Egg-Moves work with Smeargle. Just so you know, Smeargle can't learn any Egg-Moves, however Smeargle can pass down Moves that it acquired via Sketch if it's offspring can learn it as an Egg-Move.

Hope I helped.
