Really how you breed the kitties is up to you. I personally have lines that I breed for a pure fur. As there is nothing more annoying to me than to finally get the traits I want only to have a recessive fur pop out that I absolutely don't like.
Just don't get into a mind set that recessive is better. There IS NO better trait. The team does a wonderful job with them so choose what you want. Basically it's knowing what you want, how to get there, and knowing what you have
Now to show a Bengal Tawny 'pure' fur I am providing a visual below. Pure just refers to the shown trait is also the hidden trait.
Row shows Genesis Smokey II and hides Bengal Tawny
Emelene shows Genesis Domino II and hides Bengal Silver
Both their offspring Manara and Goldwyn got Emelene's shown fur (Genesis Domino II) and hide Row's hidden fur the Bengal Tawny
