What are the chances that this Pokémon’s ability will be passed down to the offspring?

Question

So I’m going to breed a Bidoof (With a Ditto). It’s a Female with the ability Unaware. Bidoof has two abilities, Simple, and Unaware. Will the chances be 50/50 on the ability being passed down? If not, why? This is in Pokémon XY.

If you give it an everstone it will always pass it down

Everstone works for natures not abilities.

Oh, right

Answer 1

No, breeding a Pokemon with two standard abilities won't give a 50/50 percent chance of either ability in Pokemon XY. According to Serebii,

"If the mother has their ability in slot 1, then the baby has an 80% chance of hatching with that ability, and 20% for the second ability and viceversa if the mother has the ability in the second slot." Source

Before Pokemon Black 2 & White 2, the baby Pokemon had a 50/50 percent chance of inheriting the mothers ability.

Thanks for the information! Guess iĺl go catch another female Bidoof with the ¨Simple¨ ability so I have a better chance of getting a shiny Bidoof with Simple once I start Masuda Method breeding it.

Yeah it's easier to obtain another Bidoof in the wild than to breed for one. Also, don't worry I had the same problem too, with my Goomy.
