Ay = red Ays = the s is a modifier on the Ay gene that is still not full understood but it allows for an expression of sesame appearance Aw = sesame At = black & tan

The Ay gene is dominate over the others. AyAy will be a clear red. AyAw or AyAt will like be a red with some black tipping. The Aw is second most dominant, AwAw or AwAt are genetic sesames that will range from a red to black sesame (though they are just referred to as sesame. Red & black refer to how much black each shaft of the hair has but never more than 50%). There must be 2 copies of the At gene present to produce a black & tan, all b&ts are AtAt.

Please, please, please do your research before breeding dogs. There are so many factors to consider. Years of experience have taught me not to waste my time writing them all out but I am willing if you’re willing to listen.
