What is generation and how to read the letters in the pedigree?
When Savannah is crossed with Serval, as a result we get kittens F1A. ( in past the same was used for crossing Serval with other breeds)
"F" means "Foundation".
"1" means the first offspring of a Serval.
"A" means that one of the parents is not a Savannah.
You can also see: "B","C","SBT".
"B" means that somebody of grandparents is not a Savannah.
"C" means that somebody of great grandparents is not a Savannah.
"SBT" means that 4 generations are purebred Savannah.
If you see F3C, that means that the kitten's great grandparent is a Serval. F3B means that somebody of the kitten's grandparents is not a Savannah.

"Outcross" means crossing with the other breed (it is allowed during the process of formation of the breed)
F 1 A x Outcross = F2 A Kitten
