Nothing, legendary Pokemon, such as Mew, Mewtwo, Ho-Oh, and Lugia cannot be bred with anything.
No, Legendary Pokemon cannot be produced by breeding. No legendary will produce eggs with Ditto, apart from Manaphy, which will produce Phione eggs.
I don't think you can "breed" Pokemon at all in heartgold. well i am somebody different from the other guy but yes you can i breeded twice in pokemon heart gold my fist one was 2 pikachu's and my second one was 1 ditto and a pikachu to get a pichu and it worked :)
Mewtwo is a legendary Pokémon, therefore it cannot breed. If you want a Mew you'll have to trade it from one of the previous games.
Try going to dragoart.com and search Mewtwo
you can't breed pokemon to make a ditto, but you can catch a ditto at route 218 using a PokeRader.
Put mewtwo in the daycare with a ditto. I did this with other legendary Pokemon and it worked

Nothing without cheating due to the fact mewtwo cant breed.

Nothing, because Mewtwo can't breed. None of the legendary Pokemon in the game are able to breed.
Parasect, magneton, ditto, psyduck, golduck, machoke, mewtwo.

Mewtwo cannot breed with any Pokémon including Mew. The logic behind it is first its a Legendary and its a clone.
From what I heard you can find it in the Cerulean Cave, but you can't own any max repels, or escape ropes. Also don't save the game until you reach the room. (Where Mewtwo Was) Then have Mewtwo first in your party and Ditto 2nd. Mewtwo and Ditto will start to dance. (They must be happy to dance.) After they've danced a shiny light will appear 3 times. Then a Mew will appear. (Make sure you have a weak pokemon, because Mew is a level 1) So make sure you have lots of ultra balls. :)
ditto cant make eggs with legenary Pokemon like, mewtwo, mew,moltres,articuno, zapdos,ect. also, mew is impossible to get in fire red/leaf green, without getting it from an event, or cheating and/or trading with someone that cheated.
Well you can catch ditto right outside of canalave city. You should have a 3% chance of one appearing. Also you may want to catch one in the cave where mewtwo is in soul silver or heartgold.
Ditto, Electrode, Kadabra, Mewtwo, Psyduck, Golduck, Magikarp, Gyrados, Parasect, Magneton, Golbat.
