Well neutrals are neutral so they get nothing they are average at everything and have no racial abilities. The main races get racial attributes modification. How much depends on how many points you selected in the player set-up screen. They can also get special racial traits such as organic or religious tech areas. You can see this in the game by right clicking on their picture in the diplomatic screen or right clicking on the empire flag in the upper left corner of either their ship or planet picture.

They don't get any bonuses more than what you could pick unless you give them a bonus in the players screen before you start a game. If you do that they seem to have extra research points and resources.
