In transgenic mouse work, what generation immediately follows the founder?

Explanation:
The first filial generation (F1) is the generation that immediately follows the founder. The founder is the original transgenic mouse carrying the transgene in its genome, and when you breed that founder to a non-transgenic partner, the offspring produced are the F1 generation. These F1 animals are the first to inherit the transgene and are used to establish and propagate the transgenic line for future generations (F2, F3, etc.).
