Answer:
The original mice that are crossed are called parent generation. The offspring produced from this cross are called Fâ generation or first Filial generation.
The first set of organisms crossed are called parental generation and is denoted by P.
The offspring produced from this cross are called as first filial generation or Fâ generation.
The offspring produced by selfing or cross pollination of organisms of Fâ generation are called as second filial or Fâ generation.
The example is shown in the figure attached below.

The original mice that you cross are called the parent generation. While the offspring produced from this cross are called the Fâ generation or the first Filial generation.
What is Heredity?
Heredity may be defined as the branch of genetics that deals with the aggregate of all biological strategies by which distinct characteristics are transferred from parents to their offspring.
The first set of organisms that you cross is called the parental generation, while the offspring produced by the mating of this cross is called the F1 generation.
When this F1 generation is again selfed, it produced the offspring which are classified under the category of the F2 generation.
Therefore, it is well described above.
