The P₁ generation indicates the initial parental generation of a family or group being observed for a specific trait or traits. So, Adele and Adam are the P₁ generation. The F generations are the succeeding generations of offspring or progeny produced from the parental generation. Each succeeding generation is designated by a numeric subscript. The F₁ is the first-generation offspring or progeny after the parental generation (Barbara, Brenda, and Beverly). The F₂ indicates the second-generation offspring or progeny (Carol, Cliff, Carl, and Charlie). The description of this family does not include the F3 or third generation.
