If two Pokemon have a dream world abilities will the offspring have one?

Question

I have a ditto and Typhloshion with dream world abilities what is the percent of the offspring of having it
The game I'm playing is white 2

Answer 1

The offspring is not guaranteed to have it's Hidden Ability as there is a 60% chance that the mother will pass down it's Hidden Ability to each of it's children.

In Generation V, female Pokémon with Hidden Abilities have a 60% chance of passing on the Hidden Ability to their offspring when bred with a male Pokémon from the same Egg Group.
