The F1 has the highest percentage wild blood (usually 50%) her offspring would have 25%, and so on. Usually the first 4-5 generations of males are sterile.
Actually, the F stands for F I L I A L which designates the generation or the sequence of generations following the parental generation. Filial, in Bengalese, indicates the hybrid generations, 1-3. Specifically referred to as: F1, F2, and F3. TICA has their own term for filial adding to the confusion. Foundation is a confusing term due misinterpretation. Generally a many 'new' breeders description of a foundational Bengals is being F1 through F3. Yet to the informed breeder foundation relates to "foundation breeding stock", in any breed, regardless of generation or ancestry. A foundation stock Bengal could be an ALC, F1, F2, F3, or SBT. However, TICA registers the filial Bengals as Foundation Bengals. Consequently TICA refers to filial only as foundation this is where confusion can set in. Breeders that have been around awhile and bred other cats commonly refer to cats in their initial breeding as "foundation stock".
