What is the correct genetic designation for the initial founder of a line of transgenic mice?

Explanation:
The initial animal that carries the new transgene is designated the founder generation, F0. This label marks the first individual in which the genetic modification was introduced. When that founder is bred, its offspring are the next generation, F1, followed by F2, and so on. The other terms listed aren’t used to name the founder in standard transgenic nomenclature. F1 refers to the first offspring after the founder, not the founder itself, and N0/N1 aren’t the conventional designations for this context. Understanding that the founder is F0 helps you track how the transgene passes through generations as you establish a stable transgenic line.
