You can't. If you migrate Pokemon from the gameboy to the DS, it notes that "After any Pokemon are placed in your DS game, you cannot return ANY Pokemon to your GBA Game". I have tried to do it many different ways, but to no avail.

No, since Pokémon Yellow is on the Game Boy Color, and Pokémon Fire Red is on the Game Boy Advance, it is not possible to trade between these games. The Game Boy Color is not compatible with the Game Boy Advance.
