Best Answer

F1 refers to the first generation of offspring (children) of two individuals. It can refer to many different organisms, not just animals.

P would be used to indicate the 2 parents, and F1 are their children (and F2 would be the second generation of offspring of P, so P's grandchildren and F1's children, and so on)

These P and F terms are terms from the field of genetics, used in the study of natural populations and crossing experiments. A famous example is the crossing experiments with peas by Gregos Mendel, who was the fouder of these types of studies.
